I fitted a York OBA system recently. Here it is:

and more info on the bracket can be found here: https://www.yotatech.com/forums/f116...r-22re-152143/. I must warn you though, that I build a bracket as per instruction off PirateBB, and it didn't fit, the one below I designed and it actually works on a stock 22RE with OEM-height engine mounts.

Used these sites when figuring out my OBA:

I recommend doing this mod to your compressor as well so your compressor oil doesn't spill out down the air line.

On finding the compressor:
http://www.links4jeeps.com/writeups/...ork_Donors.php

Compressor: Full-sized York off a Volvo (I think, I bought it from a guy who had it in the garage)
Bracket: Adapted from a 22RE A/C bracket, you need a sort of spacer as well
Air lines: 3/8"
Air tank: Air brake tank off a Ford dump truck (note: not a dumpy Ford truck)
Valves switches etc: One-way into the tank, 150psi pressure release valve, drain valve, 90psi on/120psi off

Description:

• York is belt driven off the engine in place of the stock AC pump (you can't install the York like I have with AC)
• pressured air goes down the air line, through the one way valve
• pump has a magnetic clutch that is activated by a relay
• relay is only thrown when:
  a) the day-time runnning lights are ON (always on when engine is running (Canadian spec)
  b) the switch in the engine bay next to the quick disconnect is ON
  c) pressure is below 90psi.
• air tank link to quick disconnect zip-tied near battery
• fills up a 31" tire from ~5 to 35psi in ~30 seconds at 2500rpm

cost estimate

• York compressor...................<$50
• 22RE A/C bracket....................$30
• 25' air hose, cut inot pieces......$15
• NPT fittings............................$50
• air brake tank........................$50
• air filter, pressure valves.........$40
• electrical bits.........................$50
• TOTAL................................~$300 (based on what I actually spent)
• Knowing your compressor pumps out 10X more air and costs less than half of the guys with a Viair....Priceless

Here's the measurements on the bracket.




Looks like this when you're done.











I secured the bracket to the body of the truck.
