I've been combing the site for days now and have not been able to gather enough information to come to a definite conclusion for my specific application. So here's what I've got:

First off, I acquired a brand new 80 Amp Delco Remy alternator w/ internal regulator for '64-'86 Chevys, that gives either option for single or 3 wire hookup. I am determined to use it since I've got it. The price was too good to pass up and opting for a Bosch is not even a consideration.

I have a B20B in my '65 122 and it has the ear on the block to mount an alternator.

Question is: What do I have to do to allow the alternator to mount up to the block's existing ear, and what wire(s) need hooked up on a simple connection? I would like to avoid amp idiot light issues at the same time too.

Thanks in advance!
