New here to this forum, from Boerne tx.

You don't need any adapter plate. I think 82-85 dodge d50s had the 904 trans. Mine came from an 85. The mitsu trucks used the mitsu auto trans, not the 904. And it has to be from a 2.0 not a 2.6. For a 5spd you need the 87-89 dodge d50 2.0 trans. I have one of each. The 5spd is in the truck now. I used the 4g63t 6bolt flywheel and presure plate, and used the truck wideblock clutch disc. I am running ecmlink v3 lite for engine management. I do wiring harness for the 4g63t (and na if wanted) to drop them in any vehicle. We have a big rwd 4g63 (we love all vehicles though) over at www.hotrodcoffeeshop.com
