I would look for a two piece driveshaft out of a 3/4 ton that had a th400. Problem that I ran into was I couldn't really find anyone that would take the crossmember and carrier bearing support for the driveshaft out. It could have been I didn't find the right people at the time but nobody wanted to mess with it at all. The crossmember supports the rear of the cab with two cab mounts, its factory riveted into the frame, has the metal gas lines running across it, and something else. This is the way I wanted it to get done but it didn't. I got lucky and found a driveshaft that had a longer slip yoke for a th400. It works, but its not (ideally) what I wanted and it does vibrate a little bit most the time not very noticeable. It could be worse than what it is but I do drive it with it and its been in there about a year and six months.

I had to move my crossmember back some for the transmission mount on the th400. I used a black polyurethane from energy suspension and also installed a double hump transmission crossmember. Your stock transmission crossmember should work it should only need move back just like my double hump one. I got three bolt holes to line up on mine and needed to drill one hole (d/s front).

Driveshaft universal joints if you get a 3/4 ton one, you will probably need a conversion universal joint I'm thinking 1350 / 1410 is the size difference. That will depend on what you end up with for a driveshaft and if you are leaving the stock 10/12 bolt differential in place.

As for mine its seems the more I want to do to it and have done to it I should of bought a 3/4 ton.

I also made a really cheap (10.00) kick down switch. I installed a transgo shift kit and adjustable transmission modulator valve. The transgo shift kit from Summit was like 75.00 it came with everything and a video to do the install.

I can email you any pictures you want to see about my setup or anyone else that wants to see them. Most of them are to big to load here or host.
