Denso Compressor Question
 

Are there Denso compressors out there that mate to a 3.2 but also have flared fittings versus the later O ring style? I need one if it exists.

A new or remanufactured 911/930 Denso compressor does not come with compressor manifolds (what you connect your refrigerant hoses to). You need a good used set of compressor manifolds. The manifolds are designed for o-ring fittings. You could attempt to put flare to o-ring adapters on them however your current compressor to deck lid condenser hose fitting at the compressor side won't mate up properly. Hence you need to replace that hose as a minimum. If you intend to keep all the original 1974 hoses in the car you will be recharging the system often.
