I am looking around for a manual transmission that will bolt up to the cummins.

I have a 10.25 sterling rear so I am not too worried about that. The driveshaft is pretty heavy as well.

I already need new springs on the front. I will just get the next step up in weight, as they are very stout to begin with. (the front only drops 3/4" when I lift the plow)

I can work my way around the steering.

I can use the same fuel tank. The pump is going out, but that is fine if I am going to switch to diesel.

The only part of the harness that will be reused is the in-cab portion and the lights. The in-cab harness will run the windows, wipers, dash, and blower. I am not sure how I will deal with the cruise control. I can deal with that later.

I have the ability to swap the motors. That is not a problem. I just need the money to do it. It will cost me ABOUT the same amount to do the swap as it would to rebuild the motor, tranny, replace the fuel pump and a bunch of sensors.

This truck works HARD. It gets loaded past the roof with firewood and hauls gravel, lumber, scrap, and other stuff on a part time basis. It also serves as a run around truck right now, until the car gets done. It has payed for itself many times over.

I am going to install air springs in the rear of the truck to help with the heavy loads. This truck needs some $$$$ stuck into it either way, and I want to get as much improvement as I can for the money. The ability to burn used engine oil also appeals to me. I change oil for people and this would be free fuel once filtered.
