Thanks Paul, that was the kind of info I was looking for!! Oh, these codes (L35, L48, M20 or any other), where can these codes be found (buildsheet, invoice,??). I'm getting back into the hobby (so me and my son can build something together and have a car worth something) after selling my 72 SS Chevelle 11 years ago for 8000, body off rest and all. Isn't that crazy. Back when you could take someones word for what you were buying. I think alot of people are trying to ca$h in on all this Barret-Jackson craze. It's almost put the common man out of it......
