I'll go ahead and save Mike L the trouble, here what I got from him in my PM, some good info.
"I don't really remember how much the WJ stuff ran me as I would gather parts here and there. As for the new 16's and the tires, I needed new tires anyway and figured I could use the extra clearance anyway instead of having to grind down the caliper.
As for the fab, I had a buddy weld up the over axle bracket and track bar for me but the rest weas pretty much bolt on. The WJ uses the standard size tre's like the XJ. I reamed out the knuckles to use the bigger 1-ton tre's. The tre's and linkage I got from Parts Mike.
You will need to get the knuckles, spacers, 00 and hub unitebearings, wj rotors redrilled to 5 on 4.5, etc. Its a pretty big deal to get all the parts and have them come together nicely. This was the first one I saw with the 1 ton tre's. All I can say is those ends are huge and there isn't a whole lot of room between the rotor and tre. I didn't measure but it seemed to be between 1/8" and 1/4"."
Thanks for the info!
