I've got the remains of a trashed 67 Volvo transmission out in the barn, and I'm about to take a cutoff wheel to the shaft that plugs into the overdrive, then make the necessary parts to convert it to a stand-alone unit on a separate crossmember immediately behind a 3 or 4 speed GM transmission. It's "Machine shop 101" to make the stuff to convert it to a divorced OD unit!
