That's……a darn good question. Lol. The engine had been ina few different trucks over the years, so nobody's really sure what pulleys or brackets are from what. But I believe the ramcharger was an a/c truck, but when my uncle swapped it into his d150 he put the non a/c alternator on it.
BUT, on that subject. I'm planing on fabbing up some brackets and spacers to mount an internally regulated denso alternator on jasons car.
That along with the cheap, piece of crap, all inclusive distributor for $50, should clean up the engine compartment wiring a lot.
As you can see by the pics of my car…we're kinda fussy with our wiring. Lol. Out of site. Lol
