Hi,

I'm looking to install the GM 'fender brace' (14074745) and was wondering what size bolt is used to attach them. From what I've seen it looks like GM used a bolt w/ u-clip but I haven'r been able to find the right size.

Can anyone help (or has the actual part number)?

Thanks,

John

If you're talking about the one on the pass side that attached to the cowl just inboard of the evap housing, it used a self-tapping sheet-metal type screw that went through a hole in the cowl sheet metal and threaded into the bracket itself.

On my car, it wallowed out the hole in the cowl pretty good after acoupla hundred thousand miles. So I guess it was DEFINITELY doing something; but the place it was attached to there was inadequate.

I was wrong. Actually went back and looked.

It had a stud captivated in a Tinnerman clip sort of deal, and a nut, at the cowl; and a 6mm (10mm head) sheet metal screw that went though it and into a hole drilled into the strut tower. Totally weenie. The cowl is all wallowed out around it.

There's also a brace that goes straight down from the top of the strut tower to the "frame" right next to the exh man on the pass side.
