You can change the bellhousing on the A4LD, you'll need to find a bell from a 2.3 or 2.5 Lima engine, the tranny can be from any engine as far as I know, stick with a early one, 80's to early 90's, not sure what years had gear selectors for 1,2,drive and overdrive and what years had OD activated by 12Volts, you can also apply lockup using a 12volt toggle. Look for Turbo coupes, XR4TI's, 4 and 6 cylinder mustangs, rangers, and bronco's.
you'll also need to modify the tranny mount, early 2.3 pinto flex plate should work, and lastly the A4LD yoke will be needed.
