Re: York Compressor!!!
I found a york and all the brackets in a local yard here in Tennessee for $35, they were in an AMC Hornet I believe, I got the bracket that mounts the York, the alternator relocation bracket, and the idler pulley bracket that mounts on the other side of the engine above the power steering pump. I even got the belts off of the donor vehicle and am using 1 of them as it was in good condition, the other one I was able to take to the parts store and use for size reference. I even scored the alternator from the AMC as it was still attached to the bracket.
Try this link for some picts. of a 258 with all the same brackets.---http://www.nacs.net/~djperk/Jeep/tech/oba.html
