Trans Crossmember Question

I put a LA360-A833 into a 68 Barracuda that was factory equipped with a slanty/904. I used a 73 Dart 318/904 spool-mount crossmember. So if that means anything, Ima thinking they are all interchangeable.......probably from 67 to 76ish.

But if you are referring to an O/D automatic, like an A500/518, well, surprise!! Um no. Lotsa cutting, welding and fabricating.
