torsion bar issue?

I want to thank you guys for the excellent dialog. Yesterday crossmember rot finally got to my 68 Dart (driver's side socket ripped loose), and I am trying to do a little research to see what my options are. I saw a replacement crossmember somewhere on this list, but I guess it was not for an A body given what rmchrgr is saying. Replacement would be my first choice, but I do want to get this Dart back on the road as my daily driver again.
