AC Compressor Pulley and/or Pump

Here's my thread on brackets and pulleys.

It seems like there were at least three different alternator bracket setups.

To the best of my knowledge, the one used with factory air is a cast iron piece. The reason factory air requires a different alternator bracket is that the alternator is moved forward to line up with the AC crankshaft and compressor dual pulleys.

With dealer air, the alternator stays in it's stock location driven by the water pump belt and the AC compressor gets a dedicated single belt, idler pulley and roller.

Even though my car had factory air, it came to me with dealer air brackets and pulleys (except that it had two crank pulleys for AC). It didn't have the alternator bracket with the hole in it for the dipstick. It had the simpler flat triangle bracket. I would love to know which alternator bracket was standard issue in 1965 for non-AC or dealer AC cars. Was the alternator bracket changed when dealer air was installed or did the kit work with the alternator bracket that came from the factory.
