Sanden A/C Compressor to fit a 273

The Classic Auto Air brackets come from Bouchilon (BPE) so don't pay CAA's mark up. (my brackets had Bouchilon printed right on the bracket). If you are using factory AC pulleys DON'T use the Classic Air/Bouchilon brackets that put the AC compressor and the Alternator on the same belts. The grooves are misalligned and you will only be able to use one belt instead of a pair - squeal city!!! I spent a lot of time finding pulleys and spacers to move the crank pulley, the alternator and the power steering forward (while keeping the fan in the same place to use twin belts on mine. You can't move the compressor back since it's already right up to the thermostat housing, so everything else has to come forward.
