if you need one now, your best bet is probably to find a set of originals somewhere(i heard of some people having problems with the aftermarket ones but someone might want to chime in on that) and weld a tab from a set of f-body pedals on. The f-body pedals, if i remember correctly, actually had the tab welded on from the factory, so a die grinder and some patience, a little bit of welding, etc, you should be golden. I would give you the dimensions for where the stud should be in relation to the top pivot but there is no way i can get that pedal out of the car to measure. Anyone have one handy that can give some measurements? Also, make sure you fab up a pedal stop for yourself and some pedal to firewall bracing no matter which route you take so you don't run into clutch master cylinder and firewall flex problems.
