A/C Compressor bracket

I just finished a custom AC bracket for my 64 slant engine (will post in that forum). I used a kit of 2 brackets w/ adjustable slots for a Sanden compressor, of ~1/4" steel that you can find on ebay. You must cut the plates and weld to a backing plate. There are many issues to trip one up. You want the slots oriented so you can swing the compressor away from the crank to tighten the belt. Alternatively, you can rigidly mount the compressor and share the belt with the alternator or p.s. pump for tightening, or use an adjustable idler pulley. There are York-Sanden adapter brackets that might get you started. I tried one w/ adjustable slots, but couldn't orient so the slots would work.

You need rigid mounting points, and often additional braces to prevent oscillations (in several directions). If you know Statics, there are 3 translations and 3 rotations possible that you must provide supports to oppose. Of course, the pulley groove must wind up in the correct spot, the compressor not bump into anything, and the ports be where you can get fittings on and swing a wrench. The last 2 are usually easier if the compressor is up high. Good luck. I spent way too much time on mine, but it does look cool.
