On board air set - York Compressor and 4.2 brackets
 

York compressor and brackets for 4.2 I-6 brackets
York comp #'s on metal tag
No. M 582778
Pt. AMC 5461585
Navistar Comp #'s on metal tag (Navistar is for International Trucks)
No. A 2052077
Pt. 2000820-091
Bracket bolted to the compressor P/N 3230389
Cast Alum brkt 3242191
Small slot brkt 3238456
large bracket and pulley have no visible part #s on them

Both compressors turn free, and the York has reusable fitting on the top so that saves you $ you don't have to buy fittings. I don't think the Navistar compressor has ever been use and all the mounting holes look identical to the York.
I bought this used and never installed it so I cant tell you any more about it than what you see.
$120 for York and all brackets
$40 for Navistar compressor only.
Thanks

Clutch
 

Does the Clutch engage?

Magnet works when energized, but doesn't release....I'm not sure but the pulley bearing may be froze. Called Carquest and you can buy the pulley bearing only from them. They had 2 different grades listed one was $33 and one was $75.
I replaced only the bearing on the A/C comp in my Dakota and works great and saved a bunch of $. Carquest was the only place that I could find them listed individualy. Just a tip for all you DIY'ers
