I put on board air with a York air compressor, best mod EVER done. If any of you need a York for the correct size pully I can get them for $125 plus shipping. You can do anything from pumping your tires to running air tools. AND you keep your factory A/C.

OK, I'll bite, how did you mount a York and keep the factory A/C?

Okay I'll bit, too. How about some pictures and/or a more detailed explaination.
Also, you can get the york for any pulley or a pulley for any york?

I first move the batt to the left side.next i got a pully from kilby that goes on the alt.i found a bracket from a old dodge that is for a york and cut off the shim on the top alt bolt it slid over the bracket.then i made a L bracket that goes off the a\c bolts on the ho 4.0 the two on the side cut slots in them so the york can move upand down to titen the belt. bent lower a\c hose down to so the pully on the york would fit moved rad ahead 1\4in for upper rad hose to fit. i can get the york and pully needs tobe a 6in pully to fit no room for anything bigger to fit

find a good host. Photobucket is free and lets you direct link so you can post them up here with the insert image tag... I'm curious to see this set up.

the battery went in place of the stock air box, correct?
what is your source for intake air?
the ONLY other modification to the stock engine compartment, other than the mounting setup, was to move the radiator forward?

I am deep into this project myself with my '98. I did a number of engine compartment layout changes to make room for the York. Most of them are detailed on Http://www.madxj.com in the tech section. I routed my ARB snorkel through the inner fender, through an intense air cannister, and into the throttle body. I sunk the computer into the inner fender. I moved the battery to the drivers side without any need to move the radiator although that is an option I didn't think of to create more room. I mounted an ARB compressor in the area that used to mount the ABS pump...since I had the ARB unit from a previous Jeep and it was going to be awhile before I got the York system up and running. I added 4 solenoids for my xd9000 Warn winch to the inner fender on the passenger side and finally tried using Kilbys xj kit for a York which isn't quite finalized. The combination pulley for the alternator fit ok and cleared the fan blade by 1/4", but when I installed the York on his bracket, the fan would hit the clutch on the York double groove pulley. Brad said I needed to space the fan 1/2" out from the stock mounting, but that would have put the fan too close to the radiator. Instead, I returned his kit and built my own mounting utilizing a serpentine pulley on the York and aligning it with the stock serpentine belt on the '98. Everything fit fine, but I didn't think the new belt layout had enough contact on the stock AC pulley, so I added a small idler pulley between the York and the stock AC unit. I'm now running a belt for a 95 Ford Mustang with 302. 
I also had to reroute/somewhat radically bend the stock AC lines where they pass into the condensor. I ended up having the stock system evacuated, removing the lines and bending away. I got the lines to fit, but I did have a problem with the stub lines from the condensor. One of them just points in the wrong direction. I ended up cutting it off and having a shop weld it back on pointing straight down. It was an easy mod and worked well. I got the system recharged last week and it is working fine. I still need to wire the York as well as plumb the output. The mount is done though and everything is working fine. I'll have an article on www.madxj.com eventually and have a ton of pics right now, but no place to post them until the article is done. As for the mount, I pretty much copied Kilbys mount but made the compressor solidly mounted as low as possible giving a little room before the inner fender and a bit back to align the serpentine pulley.

Hey, sense we are talking about OBA, I will show off mine too. I also followed the MadXJ write up. I love the fact that it's all on one belt. (If you notice, I still have to add a filter, in line oiler, and lots of other stuff.). Oh, to save money, I reused the orginal battery holder instead of buying a diesel XJ tray.
