Johnny. Agree with George regarding the 1-wire vs. 3-wire alternator issue. I ended up with a new Tuff Stuff 7078RC 100 amp, 3-wire alternator via eBay for $110 (shipping included). I installed a new electronic voltage regulator at the same time. I imagine The alternators are also available through most on-line performance shops. The RC version is chrome. So, it looks really nice when you've got the firewall cover off.
