The part you have in your picture is the subframe crossmember as others said. Nothing to do with the trans and the engine does not mount to it either. Can't trust the big catalogs with names nor applications. They are wrong often.
It is available repop and plentiful used. It is basically the same on all Nova models 1962 - 67, with minor variations for brake lines, ground straps and random crap like that. SCHWABIE will have the right part (he knows the cars) and I have a pile of used GM ones.
If you need the trans crossmember, that is a different discussion.
