Trevor, just a suggestion but maybe send a pm to One True Chevy Girl about your needs. She and her husband seem to be tapped into this era of Corvette and may be able to offer some advice and or direction. She is a very nice person to boot.
She was on the forum just recently so she may be in contact in any case. Graham (Nascar03) has been a long time member of a number of Corvette clubs, he may be able to provide some direction as well.
Good luck with your search, if you get frustrated with it I will come and get rid of it for you. No charge.
