Stop in for a cup of coffee

I agree. something is not right. Looks like GM. I know C body is a frame car. Not uni body.
maybe in 64 but in 66 they are uni body with a bolt on subframe. My Polara is a 66

I know 65 is similar to 66 but has a ton of one year only parts and I don't know much about 64 but I think its totally different.
