Yea they should bolt up mo problem, they might be just a tad wider, I believe the Rubi axles are at 62"
You'll need the (2) air pumps for them that typically mount on the T-case skid, but might be better off moutning in egine compartment.
I think that you'll also need to chage driveshafts, I dont think that the earlier TJ's are the same length and u-joints.
Hopefully the axles come with the air lines and wiring harness as well for them. Otherwise will have to wire them and install your own locker switches. Have them on separate switches is better anyways.
