Ok, I've been doing research and I found a post on D50 that stated that you can use an alternator from a 1990 Mitsu Van. And it's a direct swap.
So being the type of person that needs this sort of thing... I ordered one! And I must say "IT'S PERFECT!!!" I had to press the bottom spacer out a smidge with a vise.
BUT IT WAS A DIRECT 75 AMP SWAP!
No more problems with running the A/C, headlights, stereo, electric fan, ect. Voltage stays constant now!
Mine is a 2.4L 4g64 (2nd Gen)
Not sure if this swap will work on the 2.0L or 2.6L vehicles, nor do I know if it will work on the 1st Gen's
BUT I CAN CONFIRM IT DOES WORK FOR A 2.4 Second Gen!
