A: You can swap the clutch for one from the same kind of unit and serpentine belt too. From: Frank Swygert <farna@xxxxxxx> To: mail@xxxxxxxxxxxx Subject: Re: Aftermarket AC You've got the right idea Jim! On my first Classic wagon I kept the Jeep 4.0L AC compressor and attached it to a universal type under dash unit inside the car. Required custom hoses though. Southern Air and Vintage Air both have the universal evaporator units. Just get the compressor bracket from any AMC six (pre 74 -- bracket locations changed in 74!). You can buy an adapter for a Sanden compressor (originals were the big York piston compressors -- look like 3.5 hp BS lawn mower engines, only aluminum!). Just make sure you get a compressor with a V belt pulley.
