Air conditioning options?

Nostalgic AC Parts shows a Sanden bracket for a slant PN C3001, $225. Hard to make it out in the grainy photo. Next photo is one that member Charlie_S sells (or sold). Both add an adjustable idler pulley. Next photo is one that member Ahmed (Malaysia) made. Simplest method if you don't have power steering. A York-to-Sanden adapter ($40 ebay) might be easily modified to mount there.

Final photo is my cheap approach - brackets for a Sanden compressor I found on a Volare at PickNPull. A sub-bracket further out mounts a Saginaw power steering pump (mine is manual). Don't know if a factory setup, and haven't installed yet.

With the compressor set, I bought a vintage under-dash knee-knocker on ebay. I will make my AC hoses. Still looking for a condenser.

A complete kit usually costs >$1000. You can piece together much cheaper if you shop around.
