OK, so here's the deal...I got a trans. case skidder off a 91 troop in the local salvg. yard. Initially it looked like it would bolt right up...wrong.
Found out later that the holes in the crossmember that lined up weren't threaded ...
So, with a bit of contour relief cutting on the existing "skid plate" (if you could call it that) & a little welding...I answered my question. Yes a 91 plate will fit, but not easily.
Also found that my welding skills have "left the building" since the last time I welded anything (about 8th or 9th grade), It's ugly, but at least I've got SOME protection from the scenery around Moab.
