After having my alternator (square back) bench tested at three different locations, I have accepted the fact that it needs to be replaced or rebuilt.
I was looking online to see what is available and I found some replacement alternators on summit that are internally regulated. At first thought, this sounds like a great idea. But, without a remote sensing capability, it may not always produce the desired output.
What are some things I need to consider before buying one? I have determined my existing alternator is probably a 60 amp and I don't want to go much higher than that (probably go with 75 amp alternator). If you have tried one (or not), I would like to hear your thoughts on the idea.
Thanks

No. The voltage remains constant but the current flowing to the battery is negligible. Lead acid batteries love constant voltage sources while NiCads, LiOn and some others like constant current sources.

The biggest drawback of internal regulation is the heat generated by the alternator does not contribute to the longevity of the electronics in the regulator. That is why Mother Mopar did not do that when they invented the first mass produced standard equipment alternator.

I have a Internally regular Delco Remy on my 440 and its been there for 13 years. Never given me a problem, always given me 14.6 volts ...I just have to rod check when I start to turn it on at 1500rpm...Custom made brackets for this.
I installed the single wire Powermaster 140amp on my buddy's 72 Roadrunner about 2 months ago and he loves it too. Just remember to run an inline MegaFuse just in case something lets go and you don't run mass Voltage to the battery..Stock bracketswork for this but you have to remove the pulley & 3-bolts to rotate the housing to clear the rear terminal.

I've sold hundreds of the bracket kits over the past 10 years to adapt the Toyota Denso alternator to SB, BB and Hemi engines. Most everyone is really happy with the improvement. The Denso design reflects several decades of engineering development over the original Mopar design but it still has the look and reliability of an OEM part.
 As previously mentioned I am one of those really happy people. Thanks for engineering those brackets!

According to the Mancini site, the brackets will not work with a driver-side inlet water pump. Of course, that is the style of water pump on my car. Dang' it!

My radiator (expensive aluminum version) is a driver side outlet, which will make it a challenge to cobble together a lower radiator hose if I decide to switch to a passenger-side inlet water pump. 
Do they sell a lower radiator hose for what I need? If not, has anyone cobbled one together to get a newer style water pump to work with an older style radiator outlet?
Is that just because the fore and aft spacing is all setup for a aluminum 70-up water pump?
I mocked up and ran the 45 amp Suzuki Samurai Denso alternator on a 68 Cast Iron water pump. You just have to do the spacing yourself and modify some brackets. Didn't really modify the 3 bolt alternator bracket at all for this.
The alternator need to be moved back about equal to a full groove. There wasn't much space behind the alternator at all.

Another shot showing pulleys and brackets better.
Was mocking up the alternator and MSD E-curve on the old motor first. Just to make sure there were no issue on a new motor start-up.
You can really see how the alternator pulley is too far forward (...or the fan pulley groove is too far back)
