Alt replacement

You can see on that pic that the old style has a grounded field on the left side, its actually a brush setup that just attatches to the case where the newer style is insulated from the case for a wire to be hooked up. I did that swap on my 69 Dart, just as Cosgig said, get a wiring harness from a 72 or newer and wire it in. Mine looks like it was born there and all stock!! BTW if you go to the parts store and tell them its for a 67 car you will get the older style so if you want the newer 2 field alt then tell them its for a 72 or later. Greg
