Re: Paxton SN-92 idler pulley problem

I am the original owner of a 1991 Firebird Formula tbi with a Paxton SN-92 supercharger. The idler pulley (not the drive pulley) that came with the supercharger has failed. I can repair the pulley, but the unique bolt/shaft that connects the pulley to the plate that holds the supercharger is beyond repair.
I installed a spare pulley that I purchased years ago, but it is unavailable now.
I have searched the internet for a replacement of both the pulley and bolt/shaft combination or separate bolt/shaft, but no luck. If the pulley fails again, I wont be able to use my supercharger.
Any ideas on some kind of fix/replacement?
The pulley is 6 rib and 2-1/8" diameter.

Thanks,
305tbi

Give JB Performance a call, wouldn't be surprised if they had a used one lying around...

They might even have another option for you.
