Inspired by @themorb 's work, I set about to do the same... shoe-horn a York 210 AC compressor as a kick-ass on board air setup and RETAIN my air conditioning. Living in Kamloops summers with 3 little kidlets I definitely need to keep the AC. Here, AC > OBA.
I followed the same blueprints as Nathaniel (ok, I printed a bunch of his pictures and eyeballed it, then proceeded to ask 1,000,000 questions). I made only a few changes, such as using countersunk bolts to hold the 1st section bracket to the York, and utilizing the 1HD-T Denso top plate (Nathaniel used a FJZ80 one).
A friend down the road from me runs a CNC table, so this definitely helped. I then sandwiched the York between the relocated Denso AC compressor and the engine, re-located some of the electrical from the right side battery box, re-ran the alternator cable and Denso clutch wire, and strapped a longer Napa V-belt over both pullies. The OEM idler (tensioner) was moved to the custom bracket and used to tighten the belt.
I ran electrical (Switch on dash --> fuse + relay in custom Toyota additional fuse/relay box --> pressure switch) and included a line to the VSV idle up circuit with a couple diodes, so the activation of the York clutch would automatically idle the truck up.
I ran 3/8 air line to an air block I mounted on the firewall in the engine bay, which held the pressure switch, an extra Milton quick connect with adjustable pressure for air tools, a high-flow safety release valve, and a gauge... then from there down along the left side frame rail (encased in 3/4 split loom) to the back of the cargo area to a 200 PSI Viair hot dog air tank and Milton air/water/oil separator. From there back along the same frame rail run to the front bumper where I mounted a Milton quick connect.
The york is snorkel-fed clean air via a JIC bulkhead fitting in the middle/bottom of the truck's airbox.
For the Denso AC top plate, I had to get the low side fill shraeder valve cut and welded closed (aluminium) and an AC shop to install a new in-line fill port in the low side hose near the turbo. The high side line fit with a small tweak of the hardline. The high side fill port is accessible beside the airbox.
Initial air-up tests were impressive to say the least. At idle (up) ~1,100 it took about 45 seconds to fill a 33 from 16psi-40. Then using my hand throttle, at 2,000 rpm it took 23 seconds :O
Bought 3 belts, returned the 2 that didn't fit
