I will have to say I am pretty darned sure those are AMC wheels used on AMC's from the late 60's through early '70's. A better picture would tell, but at this time I am like 99% sure. They would have orignally had a small chrome center peice and chrome beauty rings on them. Also to mention I think they would probably bolt right onto your car. Search some AMC pictures and you may be able to find them. I know the '68 Hurst Rambler had them that looked very much like yours, also have seen like sets on '72 Javelins.
I may be wrong, but they sure rang my AMC bell when I saw them.
