You would have to change rims to the new pattern, and get TJ/XJ front bracket kit for the front axle.
They would fit no problem, but they are a shade wider then older jeeps. Maybe 4 inches. You can either add a lot of width with that, or run a really deep backspace wheel to save on bearings and balljoints.
Evolution, Lemonade Jays shop, National 4wd, or modern could all handle the work.
The user here called Spot, could do it as well if he is looking for side work.
Any of the above will be charging a hefty sum to do all the work, as it is quite a bit of fab.
