It would be for the rear. Leaf spring setup. If I can find the right yoke for my case it should work fine.
Dana 20 10 spline, 1⅛ diameter. The only way I've found so far is to buy the AA heavy duty output for $550.
I just called them, they've got several different ones for dana 20's for decent prices... So I'll buy that driveshaft from ya. I'll shoot you a pm with my number. I sold you some doors a few years ago so you might have it already haha!
