I saw a dual compressor groove drive setup on a Chevy site where the spare groove drove an added alternator. To my thinking, it was a somewhat bulky arrangement due to how they mounted the alternator but is an option. Since there are only two grooves on the crank pulley, would be interested to see how and where your installer is planning to drive the compressor --- via the PS belt position or the fan/generator position and the belt routing. Some have managed to mount and drive a compressor using a longer belt and stock everything else. Makes for a very long belt and interesting tensioning though. Both stock crank pulleys are the same size -- slightly larger than the AC pulley would be. Although the Sanden can handle it as compared to the older reciprocating piston units, that smaller pulley makes for a bit less stress on the compressor and less HP required to drive it.

Am curious to see what your installer comes up with for this application and Mike's mount. I keep hearing of another professional mount in the works but so far, no other info. Didn't know Mike was making any so with Nordstrom, his would be a third option if the other one ever surfaces.

Pretty much all hoses are cut and made as needed so as long as your guy has the proper beadlock crimper and fittings, there should be no issues there. Not too sure I would trust the old type screw hose clamp and fittings though--particularly if you are using R134a. If you would be more comfortable with professional hoses, then your guy could order custom made from Coldhosehttp://www.coldhose.com/custum-ac-hose.php or Rays Auto Airhttp://www.rayeveritt.com/Parts/Hoses/Hoses.html Not too terribly expensive but would take some added time.

Would be interested in seeing some pictures when you have it done.
