trying to by a set of buckets for my 65, found a set but they may be out of a 64, 65 or 66 they have metal backs and a silver push button on the top part. anyone know?

A 64/65 seat's are on the same frame just different pattern vinyl covers. you can widden your search to the BOP car's of those years also. 64/65 did not have metal backs or push release buttons.
67 strato bucket seats did. if in fact their Chevelle or BOP A body seats.

Some of you resto houses have online catalogs with pictures of their interior kits. OPG. Might give you a better idea of what your looking for.
