You know Tassie Nick, its quite amazing that the race cars that did survive even made it at all, and the effort you are putting into finding your uncles long lost Camaro must be commend, and there's all possibility it just didn't survive!! once you get to that stage, and only you can do that!!! a very well built replica with all the information you have would make for one fantastic recreation of the said Camaro, that's what i myself would like to see!! after all if its long gone, then no one can have it!! a replica from the same family will certainly suffice. Food for thought?
Just my opinion, but keep lookin.
