Voltage regulator for 360 LA

OK so does this still have the "one field wire" alternator?

You need to make some checks EXACTLY but first I have to know WHAT you have. So the choices are.........

1.. A...what alternator AKA grounded field as 69/ earlier system..........
B....isolated field AKA 70 or later has two field terminals
C....Some aftermarket alternator like Delco/ Denso/ ?

2...What type regulator AKA
.....A....69/ earlier Mopar
.....B.....70/ later Mopar
.....C.....Some other third party

talks about the earlier so called "round back" alternators and single terminal field

talks about "round back" and "square back." "Round back" can be grounded field or isolated field, but all "square back" are originally isolated field. Isolated field units can be grounded to operate with a 69 regulator, BUT ARE SOMETIMES grounded BY MISTAKE meaning a 70 regulator designed for isolated field will be ineffective and severely overcharge/ over voltage

What would be really helpful is a photo of your alternator and regulator
