The NV4500 is out of a Chevrolet two-wheel drive.
You might have to work a trade to get the dodge transmission. The chevy version has a shorter pilot shaft than the dodge version. This makes it really difficult to use an adapter plate. You also have to work around the Velocity sensor. I suppose you might be able to boar the bellhousing out to the size of the bearing retainer, and drill and tap new 1/2 inch 13 mounting holes. Is this the earlier 6.34:1 first gear transmission, or the later 5.61:1 first gear transmission?
It may be possible to switch out the pilot shaft for the later one, but not for the early one.
