I am changing these rusted reinforcements and one supplier, Corvette Central offer these as early or late. We think it is the thread size of the early and late seatbelt bolts.They said that my Vin 416211 was a late car but the old plates that have been removed are 7/16"UNF , not the later 1/2"UNC that are on a 1969 car we have that take the larger hex head bolts. All other suppliers seem to just supply one type.
If this is the only difference I will get the early ones against their advice.
Thank you John
