According to AUTHENTICATION LIBRARY VOL 1 by Al Grenning & Roy Sinor 490= Vinyl C=Red does not identify G. A significant number of known-to-be-original 1963 Corvettes have interior trim designations that differ from original tables. The new system went through growing pains, and errors obviously happened. Hope this helps.
Not way off-base. K3 is a week, not a date. 3rd week of July 1963. Thanks so much for that picture of the other trim tag. That coupled with some off-line messages from members are very encouraging and informative. Cheers!
Yep, not way off-base but off-base nonetheless. K3 is not a date it is a week. 3rd week of July 1963.
DAMN it, that's twice in the last couple months that the '63 date coding has kicked me in the behind. Of course you're right -- I should have looked up the code rather than rely on any sort of code standard.
