273 V8 to Slant 6 Swap: 1965 Dart

What parts would I need if I wanted to replace my 1965 273 V8 engine with a 1975 slant 6 engine? The slanty has an auto behind it, while the 273 has a 3 speed on the tree, which I would like to retain. I think it's an A-745 gearbox.

Would the Slanty bell housing bolt to the A-745 gear box? If yes, would I be able to retain the V8 Z-bar linkage if a slanty bell housing was sourced?

Hot rodders do crazy things, so don't ask why yet. lol. Not worried about the gear ratios at this point either. Thanks much.
