35 amp? Mine came with a 45 amp stock on 1st gen.

When you get your answer, depending on which alternator you decide on, maybe try rockauto or possibly somewhere that the price doesn't empty your wallet. When you get your new one, you want to bring yours in to match up casing.
1st gens were able to switch out to a 100amp off the 1990 Mitsubishi Van and 87-89 Starion, both 100amp. Depending on if your switching from another vehicle's alt and going to upgrade yours for higher amps will decide on your amp plug, pulley, and mounting ears.
Just for example which I am not sure this is what your searching for.
The 1st gen upgrade to 100amp has some changes to do before it fits. One being the plug in the back. Though I think yours has the right plug fitting for a straight swap. The next thing to watch for is the mounting ears. These should be in the same position so you don't end up having to buy a shorter or longer belt if the upgrade is different. Last thing would be the pulleys. Serpentine or V belt design and they also come with internal pulley fans and the external pulley fans blades. Other then these things, the swap isn't hard at all.
Here is an image of the 1st gen alt and the upgrade to 100amp.

I also have a question about all these alternators you go through. Didn't these that died have a warranty on them at all? Going through them like you have, I would purchase the extra warranty just in case. I also would try to correct the problem you must have with electrical so as to not kill any more. These things are not cheap and I'm sure it must be a headache to have to keep replacing.
Anyway, I am not sure if this will help or if this is what your trying to get an answer for. Mitsubishi alts are not that different from each other and your truck is in the year that it should be an easy upgrade to higher amp if your doing that.
