I managed to grenade the R&P in the rearend of my tow rig on the way to Harlan this past weekend. It's a '93 W-250, 5.9 CTD, 4WD, extended cab, original Getrag truck but it has an NV4500 swapped in.

I know the ratio is 3.54, and I'm pretty sure it's a D70. I'm just not sure which 70 it is. The truck is still in Harlan until I can go get it this weekend, so I can't look up the BOM.

My main question is whether or not R&P's are the same for all the variations of the D70?

It should be a 32 spline D70U in the rear if it's stock.
As for the gears, I think that they should be universal, only differences I've read of are carrier related.

I was thinking 70U, just wanted to confirm. I guess I'll start the search for a R&P. Thanks.
