Most any of the AA or AJ body Mopars (Chrysler LeBaron Convertible, Coupe, Sedan; Dodge Spirit; Plymouth Acclaim), as well as select Dynastys, New Yorkers, and Dusters, will have a 3.0 option: Same motor as the Monty/Raider 3.0, but with the exceptions noted by others (different cams, oil dipstick, etc.). The Mopar version of the motor came with power steering as standard, so a single belt wraps that with the rest. A/C was optional, so that has it's own belt, like the Montys.

It wouldn't surprise me if your oil pan was a straight swap to put the dipstick on the "proper" side, but with the space under the Monty hood, it shouldn't matter left or right.

Interesting tidbit: I'm under the impression that the 6G72 was conceived and designed as a FWD, right-side facing, right-hand drive motor. This would put the power steering pump on the right-hand side near the steering, and the A/C compressor near the front and the condenser.

When the same engine is turned to face forward, with left-hand drive, the power steering has to cross to the left side of the vehicle, while the A/C has to cross over to the right side.
