Congrats on your project however... do the exterior also (because of the rust there) and it'll look tits! Good luck.
Think cuda and Belair are 64/65, blue one is Biscayne don't know year. Belair is in worst shape, one side dented. Interior on all is totally burned from sun. Cuda has V8 engine, think other 2 are 6 cylinder. Would have to look. I am not familiar with this old cars so don't ask me some shit only old people born in US know. Mice living in it probably knows more than me about it
