puttin a 4.3, 700r4 and 241 t case set up in my 91 limited and was wonderin if any one that has done this had i good way to do the motor mounts the trans x member is no prob just tryin to find the best way to mount the motor

 

Well if you get 2 2x4's and lay them across the frame rails and put the engine on top and duct tape it down it'd hold down great!

As for motormounts try advance adaptors, they may have something related. if not you may have to fab something up

 

someone else on here has a 4.3 in their cherokee. can't remember who though
