Does the LWB have bouncy and HL washers? Also, the V^ front diff is different from the 4-cyl. Thinking of an ARB for thr front? You'll need the V6 front then.

Also, you can fit a Quest LSD in the V6 front. You'll need either of the CVs/centershaft, depending on which year Quest donor. 87 needs 4-cyl splines, 88-89 needs V6.

If you have the time and enegery to part it out, you should be able to get all thge parts you want, and the the $200 back, if not more.
