Polluting my charging system:
I had some pretty poor wiring between my alternator and Regulator. I went searching the wrecking yard for replacement harnesses and came up with a couple. They had some differences though and made me uneasy about using them. I ended up installing a GM design one wire alternator today. The pivot hole needed to be drilled out from 3/8 to 7/16. I was told I might have to grind on my adjustment bracket but I didn't need to. I did have to shim the bracket out from the water pump (390 motor). The alternator butts right up to the head. Fortunately the output post is away from the head. Also fortunate that the pulley lines up. I ran a wire from the alternator to the hot battery post, and a wire from one of the 4 leads that connected the alternator/regulator harness to the chassis harness, to the hot side of the solenoid. So far it appears to working great.
The battery shows 12.8 vdc when the engine is off. It shows 14.4-14.8 vdc while the engine is running with no acc. on. The wiring sure looks simpler now.

Any mid 70's alternator will work just as explained in the above post. I've been using one for years. Gotta drill 'em out to 7/16 and use an
additional shim. I use a stock 62 amp alternator and it takes two wires to hook it up. It will work on anything you can get it bolted to - garden tractors to diesels. Using a stock alternator you don't have to pay the premium for the one wire setup.
