Why not put a BL on if your going there? Granted it can't hurt to THEN put a MML on her... ( minus the obvious extra cost... but itll help the driveline angle and you may not need your T case drop
Also the T case shift linkage will be misaligned so a bracket or Novak may be involved... This is jus me but I would;
1) Pull a body mount bolt. ( preferably from most rusted/ bad one(s). if the captured nut spins, this will give you knowledge to weld in new nut(s)
2) Go to hardware store and buy 11 of those in gr. 8. (incl. nuts if needed.)
3) Jack up body and pull all bad body mounts, clean up area, and re-weld in good steel.
4) Install a BL and MML.
5) Remove T case drop and while down there install the bracket that came with said BL OR install NOVAK. (search for NOVAK install on here for detailed install guide)
6) Be Happy!
.....hope this helps
