C2-65 Brake & Master Cylinder Fire wall Bolts

[Mike M.]

I am installing the brake and clutch pedals. in the AIM I can't find the part number for the firewall bolts.It looks like maybe they were part of the assembly. Could someone tell me what type of bolt, length and thread count was used. Also the mounting for the part brake handle bolts on the fire wall. None of my parts cagalogs show any of theses bolts for purchase.
Thanks Mike

MIKE: there are four studs tack welded to the clutch-brake pedal assembly. They just require four nuts to attach the master cyl to the brake clutch pedal assm. with the firewall sandwiched between the two. mike

The studs are not there. The tack weld must have let go. If anyone knows the size length ect of these studs it would be great.
Thanks Mike

The studs were never serviced by GM. However, the thread size is 3/8-16 and the length should be 1-1/8". The original fastners were phosphate finished. You can obtain a bolt to use in SERVICE for this application under GM #3874876 which will duplicate the thread length and finish.
