I've used these before, never had a quality issue on either of the 3 cars I've put them on. 2 were mine, 1 car was a buddy's. They looked like what came off, and they worked. Then I upgraded to the 78 amp version and it's been on for a few years now. And I like the lifetime warranty. Mine were for small blocks but they were Duralast

Since you are going OE that is the one I would order: (85 M body iirc)
Robert,85 M body would be dual field,not correct.If you take one of the field wires to ground the dual field alternator will work, however the old mechanical type voltage regulators were not designed to take much more than 45-50 amps. Eventually the contacts on the mechanical type voltage regulator will fail when excessive current runs through them.

Max I did not know the old mech regs could not handle the increased field current of a later alt. One of my projects has that setup but I have not driven it very much. Eventually I was going to get an electronic (early) reg as I do not have faith in the old mech types

Why would anyone run the point type reg?Just get the new style and put the points box over it.One of the best things they ever did for old Mopars.Only reason to run the points reg is for a total show car.As for AZs allt we used a few at the shop.But we usually used Advanced because the quality was better,We didnt like having to do work twice.Rocky

Bull. The field current, which is controlled by the voltage regulator, is not 50 amps. To think that it would take the whole alternator output to charge the field is ridiculous.
The voltage regulator senses the battery or system voltage and passes enough field current to make the alternator produce enough power to keep system voltage where it was designed to be. That should be a couple of amps at max.
Now, the ammeter, as has been discussed here repeatedly, does pass through all the current, but usually it's way less than 50 amps.
As for mechanical or solid state regulators, I am sure that there were 100+ amp alternators on trucks that were controlled by mechanical regulators.
I have found that solid state regulators keep the voltage steadier, especially at idle.

My 65 has a chrome one from Summit.I converted to the late reg before the solid states came out for the points ones.Mine charges great at idle.The kids 62 300 has the OE single field with the solid state reg.His also charges as good as mine at idle.The points regs didnt really like to charge at low idles.That why they flicker so much.Rocky

Rock, I have tried 3 different single field solid state regs, still poor charge at idle..

Did you put new brushes in the alt?The 62 runs underdrive pulleys as does my 65 and both charge fine at idle.The 65 does idle high because of the cam and is a 4 speed so I dont drop like an auto.The 62 auto idles about 750 to 800 in gear.Rocky

I keep the ammeter needle close to 12 o'clock most of the time/did Nacho's bulkhead parallel bypass/clean ALL connections and terminals/relayed add ons directly to the alt. Works great/no issues and I get to keep my ammeter (I did add a voltmeter to switched 12v).

Every old Mopar i had I bypassed the amp gauge.My 65 I just took the leads and screwed them together.The 5 or 6 RamChargers I had all had burnt amp gauges.The 65s has been together for at least 20 years or more and it was burnt also.I just install volt gauges.No need for all that current to pass thru the amp meter that is a weak spot.Rocky

What's Nacho's bulkhead parallel bypass???
