I put a york OBA setup on my 80 about a year ago with the Slee bracket and pulley. It has worked great. I ran lines to the front and rear bumpers and had a coalescing filter. I didn't notice hardly any oil in the coalescing filter, mostly just water. I didn't do the mod to it with the small hex headed screw or anything, so if you worried about the oil, it's really not that big a deal. I pulled my York off what looked like a 70s ford tow truck and took it apart and cleaned it, but that's it. I didn't have a tank, but I ran the pressure at 140psi and then had a 90psi regulator on the coiled hose I plugged in. It would fill tires, run and air ratchet and impact wrench just fine. You just had to wait a couple seconds for the air to charge up while using the tools. So, to sum it up, if you are thinking about doing this, I recommend it.
