			Top alternator adjusting bolts. Sometime around early to mid 68 the bolt went from grade 2 to grade five. This is the case for Corvettes. I have seen a mix of grade 2 and 5 on pre 68 Camaros, Chevelles and Novas. (67-68 Z28's used a longer bolt due to the double bracket I will list some of those in another post)
