Ok, I know that the 65 and 66 share hundreds of the same kind of parts all over. My question is what parts ARENT compatable. I found a 66 driver with a 289 and he wants $1000 for it. This may be worth it if I can get enough parts off it. So, what parts wont match? All I know is that the rear windows (2dr) look different and so does front and rear design. Other than that is a guess.
