The 1947 - Present Chevrolet & GMC Truck Message Board Network - View Single Post - Cummins swap, I know there is a search button but the info is burried in many threads

I'm going to swap a cummins in my 72 crew cab.

The donor is a 93 W350 single rear wheel truck.

I know the dana 60 front axle is just about a bolt in with axle pads 1/2" wider and a similar track width.
I would use the dana 70 rear for the matching 3.55 gears, does anyone know the WMS width?
I would use the stock dodge overdrive trans mated to the dodge NP 205, any known problems making this work?

This is the info I am requesting.

1. Any front 4wd Differential clearance problems, I have a 2" lift or so.
2. Will the engine fit with the radiator in the stock location without firewall mods?
3. I know the Cummins is heavy so I assume frame reinforcement side to side is necessary which would probably be done with the engine mounting but has anyone used the stock cradle to mount the cummins?

Can anyone point me to these problems in previous build threads along with any other obstacles?

I don't want the install to languish, I want a quick install and on the road.

Any help is appreciated!
