2000 Dakota rear axle - limited slip questions

I bought a complete 2000 Dakota R/T 9 1/4 axle (plus a bunch of other stuff) a few years ago at a U pull. It was not that expensive.

AFAIK they are all 3.92 ratio SG, except I do know of one truck that was special ordered with 3.2x gearing.

FWIW, that Dakota axle actually measures about 3/4 inch longer than the 9 1/4 axle in my 1980 D150.

I'm not sure what a "millennium edition" Ram axle measures but it might be worth checking into.

I'd bet there were a lot more Rams made with 3.55 SG axles than Dakotas.

While swapping the axle is heavy and time consuming, setting up an R&P requires special tools and is also time consuming.
