Thorsen: thanks for the link. I think that will make getting custom hoses much easier than I originally thought. My last remaining concern is the variation of metric and SAE fittings. Then again, since I'm using a generic condenser and Sanden compressor, won't those fittings all be standard? Looking at the Ray's website, they don't have a whole lot for metric fittings.
Diametrical:
http://www.apairinc.com/iView.asp?Cat=Compressor%20Conversion%20Kits&Scat=Engine%20Mounting%20Brackets. This site has a couple adapter kits, one of which is specifically designed for retrofitting a Sanden compressor to an A6 bracket. The A6 is very long, so this bracket really just extends the mounts and moves them to the proper place so it has the same mount configuration as the A6.
