Have 84 'Kota 4X4 318 that needs its 5spd trans rebuilt. According to Dodge parts guy it has a NV3500. I can buy a NV3500 w/ low miles from a '01 Ram 2wd 318. I've only seen pictures of it, and the bellhousing is with it, and I can make out part no's that appear to be TTMT31A1305 and P52108100AD. Parts guy can't tell me if it will fit. Salvage yards (Hollander Interchange?) say 94-96 interchangeable but don't know how '01 differs. Could be something dumb like reverse switch or something minor that I can get from old one. Anybody with hands-on knowledge of this? Thanks.
