A/C on 170 Slant 6

There have been a lot of people simply re-drill the stock slant six AC bracket for the Sanden compressor and space it accordingly to line the pulleys up. If you do a good job, it will work very well. I've seen one such conversion before and was impressed. I have all the brackets to put a compressor on and a Sanden compressor. I plan on looking into it myself.
