Start with a QuickTime bellhousing to mount a T-5, and fill it full of Mopar linkage to keep it simple. You'll want to check what input shaft length is correct for the QT, but the longest - and probably most Mopar-friendly - units are the 7.85" input shaft units. These were typically used on the 94-up Mustangs, and some aftermarket units. One of the best bets would probably be the 1999-up T-5's that come behind the 3.8L V6 cars. They're rated at 300 lb-ft, and carry the PN 1352-260. They come with an electronic speedo, but maybe those parts can be swapped with cable-output parts.

If you do the swap, document the snot out of it as there are lots of other folks interested, too.
