Overdrive in Early A

42RH / A-500 in a Duster with pictures.

Here is one that might help but it's on a Duster.

Even a 727 is a tight fit in your car. You'll be cutting and beating the floor.
Is the 42RH the trans used behind the 3.9 Magnum V6? How well would it take to being bolted to a 5.2 V8?
How much different is the 46RH?
