what are the differences between the 64.5 and 65 cars? I just got what was supposed to be a 65 and am now thinking that it's a 64.5 because the window cranks are clip ons and there are a few extra slits in the radiator support. I heard those are 64.5 items only, but i'm not sure if the source was accurate. Also, was there any problems witht he 64.5 cars that were fixed by 65?
