I have an 03 dodge ram 4x4 with the 3.55 rear differential.

I blew the differential a few days ago, and cannot find a replacement locally.

I did, however, find two diffs. They came out of an 02, and 04 2wd rams.

I called the dealer to get some info, but they couldn't help me. I also searched online with no promising results.

So, my question is;

Will these diffs bolt up w/o modifications to my 03 4x4 Ram? (keep in mind, they are out of a 2wd truck)

I know the gear ratios may be different, but i don't really care at this point. I need to get my truck on the road asap.

My gut feelings tell me that the rear diff isn't any different from 2wd ones, but I need someone who knows fore sure to chime in.

Thanks guys!
