I need a part number and supplier for a clutch fork for a 68 Camaro
the last one I got from summit was to wide and curved wrong
thanks

 

GM part number and still available:
SBC/L6/BBC except 427 = 3892632
427 BBC = 3860005

 

You likely got the clutch fork for the 70's Camaro. A lot of places say it fits, and it does, it just doesn't work right for 1st gens.
Places like Eckler's sell the correct 1st gen clutch fork. It's less expensive than the oem one.
