Alternator issue..1992 ambo
I think the alternator in my ambo is headed south. The voltage doesn't remain steady anymore and pulses almost constantly. My local alternator shop is trying to convert me over to a 130 amp 3g model @130amps vs the 165amp Leece-Neville in there now. Apparently the Leece is fairly expensive to rebuild. I agreed to it, and I'm supposed to head in in the morning to have it put in, but I'm having 2nd thoughts. They acknowledge that the high output is less on the 3G but that it will have better performance at idle. I only have their word to go on that since I'm not an alternator guru. The 3G is definitely cheaper, and a faster fix, but I'm still not sure I want to go that way.
I found this replacement online Alternator Usa Industries 7767 - TheAutoPartsShop but I don't know anything about this brand. There are two options for this part, internal or external regulator, and I don't know which one my ambo would have without pulling it. Anyone have an ironclad idea?
Any viable options for a replacement other than what I've mentioned?

Leece-Neville were installed bacause they're insanely powerful, long-lasting and up to the job an ambo requires. It makes sense they're also expensive to rebuild but how much as compared to the 3G swap?
If there's an upside to the 3G is its more readily available if/when needed, probably will meet your needs. The claims of better performance at idle is one of that types advantages---do you really, really need 165 amps while driving?
If you can keep possession of the Leece-Neville I would, see what its worth as is. Maybe if the 3G doesn't suit you having the LN rebuilt and ready to install would be another option?
I think there is a vendor called DC Power with amazing alternators---heard nothing but the best about their products and services. (I'll update this with a link if I can find them again.)

Leece is kinda hard to determine external/internal. External is still mounted and wired to the alt. Need tag number off of alternator. VIN, too, needed. 165 amp is one of the options avail. but must determine if factory or aftermarket installation. Ford dealer can work with you on all of this, by the way. Meritor may have something, as well. Need more info. I don't like the sound of reducing amperage either.
