The cheap Duralast alternator I got a few years ago is crapping out. I’m going to upgrade to a 90-95 amp one this time. I’m considering going with a PowerMaster or a Remy. I have a few questions: 1.) Is Remy a reliable manufacturer? 2.) PM alternators offer theirs “externally regulated” or as a one-plug option, and i believe different options as far as where the connection is located. Which do I need? I’ll attach the pictures of my options below. 3. I know I need an alternator with the two-groove pulley, but it looks like there are different widths of the grooves to choose from. Which do I need? This is for my 1973 Plymouth Fury III with a 400. It’s all original as far as wiring.
