Dodge fronts have adapters on them. Pull them off and your single wheel. Find a dana 80 from a single wheel 5 speed truck and your good to go.

The Dana 80 was offered in SRW, but they are rather hard and expensive if you find one. They came in 94-02 Dodge trucks but only those with a 5 sp Standard tranny and either a CTD or V10.


You would have to measure for sure since I can't recall right now, but If I remember correctly my Dana 80 (97 Ram3500 DRW) was only 1" per side narrower wms-wms than my front 79 Ford Dana 60. The slight width difference will go unnoticed by most and really isn't any issue. Other than the width, the other issue you need to address would be the brakes. Since I don't think you want to run the factory drum setup that weighs nearly 100lbs, you will want to convert to disc.

I bought weld-on caliper brackets from Virginia 4x4 for a Dana 70, which allows the use of cheap and common Chevy 3/4 ton brake parts. However, I didn't like the idea of having the Chevy rotor on the inside of the hub being held on by the wheel studs alone. So I went with 2003+ Dodge 3500 DRW rear rotors instead. The dodge rotors slide on the over the hub and sit between the hub flange and wheel making them a little stronger and allow rotor replacement without pulling the axle shaft and hub. The Dodge rotors are a little pricier than the Chevy stuff, (about $15-20 each) the only thing you have change in the set-up is spacing the caliper mount up off the axle tube about 1/2" since the dodge rotor is slightly larger in diameter. I made a spacer that was an inch wide and welded that to the housing first and then the caliper bracket to the spacer.

EDIT--Another thing you might want to look into is whether the C&C axle width is the same as a regular pickup. Also, to make a Dana 80 1" per side wider use D70 SRW hubs. You will need special hub seals to swap the hubs, but that isn't a big issue I was able to find the correct seals be size on Timkens site so I now have the part number if you need it.
