what center caps to use

I have two of #1 style, and two of the one piece version of that on my car. I think the one piece is the correct one. I have only seen the two piece on F bodies. If anyone can clarify, I'd be interested to know.

Great looking car. What size tires are those?

Not sure about when they started to use the two piece one, but I believe it was in 76. I know that they are on my brothers 77 Roadrunner.

My vote is for #2. Can you get these for the large bolt pattern?
