Updating alternator - have a few questions

Watch the powermaster alternators. Some of them have internal voltage regulators and you have to read the listing very carefully to catch it.... You want the external voltage regulator if you have stock wiring...

Also, the one that you posted a link to says "One-Wire Capable: No"... If you have a 69 or earlier with the stock voltage regulator, it will take the single field alternator... It needs one wire capable...

Yeah, I've been trying to be careful instead of just hitting "order". This one is externally regulated and I should have mentioned it was for a 73 swinger. The back looks almost identical to what I have now with the power stud and 2 field connections.
