Voltage Regulator Choices

-
To the OP's original question. Best to use a voltage regulator for that alternator.
The field current draw may be, likely is, higher than what would have been in a standard optioned a-body.
If the regulator is designed for alternators that draw no more than 3.5 amps, and your alternator draws 5 amps then the VR may not hold up.

OP never answered about his alternator type and wiring. If two field wires go to the alternator, then the Vreg shown w/ triangle connector works. Best to run a dedicated ground wire to the case of the VR via its mounting screw. Perhaps a 100 A alternator draws more field current, but not assured, nor that a base Vreg couldn't manage that draw. Perhaps someone has been there. Since an OE alternator, there must have been an OE Vreg for it, with PN's. Rockauto is pretty good on PN's and what fits.

Sorry for the delay. It's a 3 wire alternator. Good tip on the dedicated ground wire. Thanks
