About to do this swap also.

I ended up picking up a whole rear end from a 93 Gen2 V6 3.0L LWB. Which is the same as a Gen1 NG LWB 3.0L

My truck is a 90 2.5TDi SWB so the benefits for me are LSD, Disc Brakes, 9" vs 8" and I think the trailing arms are beefier also. I will stick some Gen 1 LWB rear springs in at the same time for 1.5" lift.

Junk yard wanted $175 for just a pumpkin and I picked up the whole rear end from ebay for $56.

Be sure to double check the ratios before you buy anything.
