Hello, My GTO '65 has alternator (TuffStuff) with internal voltage regulator. Unfortunately, it does not charge the battery from the beginning. I do not know if it is the fault of the alternator or the electrical installation.

Truck Alternators #7127 - TUFF STUFF Performance Accessories category: 1267429

Does the alternator with internal regulator fit the GTO '65?
Does anyone have a diagram of how to connect it?

i installed an internal regulated alternator on my 65 gto a few months ago, works great.
i do not have a diagram but the only real thing different was to take off the firewall mounted regulator and add an extra wire to the positive side of the battery. i used a cable the same size as my battery cable and routed it neatly so it looked great.
