My 87 Iroc didn't have the hush panels when we got it, so I added them. It didn't have any floor lights at all though, and its not a bose car. When I added them I didn't have to drill any holes or anything like that. I'm fairly certain the car had the panels from the factory, and that a previous owner/mechanic removed them cause he was an idiot.
Also, every thirdgen I've ever owned has had the diagnostic connector cover. Along with just about every GM car I've ever owned.
Another side note is that there are MANY different hush panels used on thirdgens between 82-92 and most of them aren't interchangeable. For example, a drivers side panel from an 82 Z28 fit my 83 Coupe fine, but wouldn't come close to fitting in my 87 Iroc, but the drivers side panel out of an 86 Firebird fit the Iroc like a glove. Also, the fuse block covers are different from some years to others.

I know that most people are speaking of '87 cars, but my '89 IROC-Z has the "form-fitted, black plastic cap" with 'DIAGNOSTIC CONNECTOR' printed on it that Willie spoke of. My car is a 350 car. Is there any word yet on how to tell whether or not these cars were supposed to come with the plastics? My car has them but I'm restoring it, so I don't want to lose points for having something that isn't supposed to be there.

All five of my 3rdgen Camaros had 'hush panels'. None of them were Bose or 350 equiped. I was not the original owner of any of them. No help here...

My car also came without them from the factory. Its the L98, IrocZ, No Bose, Non A/C, pretty much un optioned car. I mentioned the non a/c thing because with the non a/c you have the underdash vents which they made different covers for. It took me a while but I was able to find covers that fit and had the openings for the vents.

I was on the team that judged you car Scott. The "third-gen" expert on our team said they were missing, I initially did not subtract any points until he pointed out the panel issue. I had an 87 IROC w/350, Bose and leather and I don't think it had panels either. However, mine went thru a number of owners before I had it. Regardless, it was the nicest 3rd gen there.
I wonder if the panels could have been out of stock for a short period of time and the factory just skipped putting them in. Was the Ohio plant still producing f-bods in 87? Just a thought...

I guess I'll play it safe and replace the panels, although I'd still like a definitive answer either way (if one exists). Maybe it's better to let sleeping dogs lie - proving that a judge is mistaken may not be in my best interest

There are two RPO codes that I have found, as to whether they pertain to the underdash panels I can't say for sure. In earlier models, there was a BS1 code for acoustical insulation (also known as Quiet group option). In later years there was another RPO code, it was B3E and was for the Noise group option. Have not yet seen anything specifically pertaining to underdash (knee bolster) panels in either the camaros or firebirds.

Well, it certainly wouldn't be your overwhelmingly vast knowledge of (nearly) everything 3rd gen
I never cease to be amazed at the endless amount of knowledge on these boards - everything from the blatantly obvious to the most miniscule and little-known facets of these cars. You guys rock

I actually found the 87 IROC-Z I've been looking for all these years, 4 1/2 to be exact! (Whoo Hooo, and thanks to SM and 87 B4Z TPI 5Spd for helping make it possible!) I will have it soon, but I already know that it has no hush panels. It's a Van Nuys L98 1SC (without D42) car. Basically it has every option except BOSE, cargo cover, hatch locking storage cover, and leather seats. It's an incredibly documented and near mint 67,000 mile original except for PROM chip and stereo/amp/speakers. So here's another untouched car without them.
There has to be an RPO or reason for it because any model could have them or not have them.

For those who don't have the lamp group option, check the under dash harness right where the hush panels screw in. I think you will find the sockets for the courtesy lamps taped up there. Thats where I found them on my car. All I had to do was add the bulbs (194) and snap them into the hush panels!

Well I thought it would be a combination of TR9 (aux lighting) and BS1 (quiet sound group). But BS1 wasn't available in '87. Anyway my '84 Z28 has the hush panels on both sides. The car has TR9, YE2 (radio), 60C (custom cloth interior). Just for the record.

I've got an 87 Iroc with a 350 L98. Has the bose, no hush panels, no lights, no brackets. ALDL connector on the right in the pic. Carpeted center console. It did, however, have the u-clips under the dash for the panels to be installed. I found a passenger panel and bolted it right up. Looks great. no spot for a courtesy light though. That's ok, because like I said, I don't have any.

So far it seems that we've never been able to make a solid determination as to specifically what cars get them and what don't.
I didn't go back and re-check every post, but from those that I did check out, it seems that all of the cars without the hush panels were Van Nuys cars. I know there are other differences between Van Nuys and Norwood cars, and perhaps this is another.
We've ruled out that it's a 350 issue, and we've ruled out that it's a Bose issue.
We haven't ruled out specific RPO codes, interior packages, or assembly plant.
This is extremely interesting for a thirdgen geek like me.

My 1990 350 Iroc with the Bose system did not come with them from the factory. The reason being with the Bose you can't open the fuse cover.

Like your car has, the courtesy light bulbs are mounted on plastic "L" brackets on these cars only.

My '92 Z came with Hush panels (I believe the floor lighting wasn't available for the '91-'92 years though). I also had the Delco Bose System with the kick panel speakers as well.....

My '88 sport coupe didn't have the hush panels when I bought it. I'm not the original owner, though. It has the L brackets for the lights and the little cap for the diagnostic connector so I'm pretty sure it never had them.

Hi all,
I am impressed that this thread was started in 2004 and had alot of interest. I have a 91 RS Vert with the hush panels but no lights, but the pocket the lights are supposed to be in are there. I have all of my rpo codes but really don't know which ones this might be connected with (B18?). It seems the interest has waned on this topic.....

I don't ahve a good answer for why or why not the hush panels were in some cars and not others, or for what year(s) they may have been included or excluded. I also do not know of any RPO time code that explicitly called for them to be installed on a car.
I am the original owner of of 1982 Z28 with the Cross Fire TBI. I have hush panels on both the driver's and passenger's sides. I did not have the BS1 option. I do have the TR9 " Auxiliary Lighiting" and 79C "Custom Cloth Bucket Interior" I also have the YE4 Raido option, which is the stero radio with the cassette player. Speakers on this car are under the dash, not down by the driver's feet. The car was built in the Van Nuys plant.
82 Iron Duke....
The top photo looks like my driver's side hush panel from the 1982 Z28. I have no idea how many model years this panel was used for. But what is the RPO for the mold, etc.
Take a look at these photos of the panel and the fuse cover....

My '83 Z28 is a Van Nuys car with Custom Cloth Interior,which included RPO-BS1 quiet sound group,RPO-TR9 lamp group and RPO-B48 luggage compartment locking storage/deluxe trim(although this most likely has nothing to do with the hush panels).She has the hush panels on both sides with the kick panel lights installed in them and the snap on ALDL cover.The sound group is the most likely candidate,to me,for the panels being there.And the interference with the BOSE kick panels for them not being there.Maybe the Bose equipped cars had additional sound deadening against the firewall.This sounds like another GM using when it's available not worrying when they weren't.

My 350 87 didn't have hush panels either. I didn't like the wiring hanging down from the pass side, so I went and got a set out of an 88 AC car at the junkyard. Well, two 88 AC cars. One's heater core exploded during a fire, so the pass panel was unusable. I had the little brackets, but removed them to put the lights in the hush panels.

OK. I have a 87 IROC fully loaded. 350, leather, bose.... The only thing it dose not have is a power antena and rear defroster(I think it was deleted because of the louvers). But it did not come with the hush panels. I don't think they would fit with the bose kicks there. I have the little meatel light socket things.Next time I am working on the 89. I'll take the hush panels off and see if they fit on the 87. Adam :-)

I have an 88 Camaro Sport Coupe. I did not have the panels or the courtesy lights. However, I inspected under the dash to find a white wire and orange wire going to a bulb holder. I put in a bulb and noticed it lit up when I opened the doors. This courtesy light wiring was installed just hidden with a mash of wires under the dash. I bought the hush panels on e-bay and now I am set. Seems to me your car probably came that way from the factory and did not have the option. Some people have upholstered center consoles and rear hatch areas as well. These were all options.

Re: Underdash plastics
I have the same question that you do. I just picked up a 1988 iroc 350 with 2200 miles form the original owner the car has the Bose sound system also. As I was going through the car I noticed that these panels were not there. I also have the coutesy lights that are mounted to a bracket and mounted to the side kick plate. I called the owner that I got the car from today. He told me he never messed with the car and no one else ever messed with the car. He said they never were there. I also have a 1987 iroc convert with 12,000 miles. This car does have them but the coutesy lights turn and snap into the sockets in these under dash panels. I'm really starting to think that some cars had them and some did not. I think the coutesy lamp mounts would be the clue if the car came with them or without them. Thanks Al

Re: Underdash plastics
I had an 85 Z back in 87--was fully loaded inside but no pwr mirrors, LG4 car. I had the hush panels in it. bought it from the dealer--I was the 2nd owner. Original owner was a mechanic at the same dealer so I'm pretty sure car was unmolested--plu it was only 2 yrs old. I also had an 85 base Camaro w/the 4 cyl. Only options were rear defrost, auto and a/c. Car definitely didn't have the hush panels--had the metal brackets for the interior lights. also had a cap that slide onto the diagnostic port. The Z had a cap on the hush panel for the port.
