FWIW,

I got the 102mm mini from like a 87-90-ish? Chevy Nova/Spectrum with the single groove steel V-belt pulley. Got it from the junkyard. Tested fine. It is the same physically as powermaster p/n 8122/8128 6.78 lbs. 102 mm. ( http://www.powermastermotorsports.co...ternators.html ) They are not one wire stock. But they have an internal regulator.

I have yet to install it or really spend time trying to figure out the fabrication of the brackets.

I think the 93mm might be an industrial application (forklift?)??

I'm looking at adapting one off of a Toyota brand forklift. An older one off of a 7 series model are rated at 37amps. My plan is install it on my drag race car.
