Custom Sanden compressor brackets for 1965 273
After these photos while plumbing the AC hoses, I decided to turn the compressor 90 deg to put the O-ring ports on the R side, as BPE suggests, to both shorten the runs and not worry about hood clearance. You can tilt a Sanden 90 deg either way until the fill port is on the side.
The rear slotted bracket might have been for a 1966-77 Ford Bronco, as I found that note with a Sanden compressor from Old Air I have on the shelf.
