I did the Sanden conversion too. The Sanden is lighter, quieter, and more efficient than the York. Plus, at least in my area, you can buy a new Sanden complete with clutch for less than a rebuilt York w/o clutch.
I had new hoses made also so I didn't use the adapter fittings.
I got my bracket from Nostalgic Air in Tampa, Fl. They make the bracket I used that allows the original tensioning setup to be used. They also make a bracket that allows the compressor to pivot to tighten the belt.
