I want to swap my rear drum brakes to caliper,what year of dodge rear diffs can I use for an easy swap on a 92 D250?

Other then going with a rear disc conversion system, the other rear diffs out there will most likely cause your truck to have a wider track width. Most of the newer disc rear axles from...Dodge, Chevy, Ford etc are all wider then our old 1st gen's.

There isn't any really easy swap. Here is my rear disc conversion thread.

Disc conversion

Since this was done I have added an adjustable proportioning valve and an inline ball valve to keep pressure applied to the rear calipers for a parking brake. Mounted both of them in the floor of the cab outboard of the drivers seat. I'll have to try and get some pics. I've also done a hydroboost conversion which I absolutely love.

I agree....going Hydro boost is a better choice then converting to rear discs.

Angry Johnny

But I did both.

The rearend in a first gen is narrower than the front a rear axle from a 05. 06 Chevy is the same with as a dana 60 dodge front and has factory disk brakes if you’re really wanting to upgrade you can buy a bolt on bracket for the front for 2 piston caliper and 14” rotors

A complete 01-02 Dana 70 with rear disc may be the easiest. Perches are the same spacing. Same yoke. Same pinion length. Same tube diameter. Even has the ABS sensor. Its about 6" wider overall though (65" vs 71") which you can balance out with spacers (front), and/or different wheels, or just not care (how I roll currently).

You can't just swap the brake hardware from the newer diff. The flanges on the axle tube are much beefier, and a different pattern/spacing. Some people have copied these disc flanges in order to do such a transplant.
