I believe 72 and up on the alternators, and they have an external voltage regulator. Hopefully I’ve helped out, Only vehicle I have in that range is a low mile Lil red express truck that’s been in the family since new. I just changed the voltage regulator on it, so I do know about that. It’ll look something like this
