Alternator upgrade 89 2.5L?

Stock is a pathetic 74 amps, I'm not looking for much, it's an 89 MJ so it doesn't require much, just going to do a few upgrades in the cooling, and stereo and want to make sure there won't be any starvation issues.

Are there any near direct swap/upgrades like the 5.9 alternator I swapped on my 96? I've looked at a wide range of GM truck alternators, but most have a slightly different front case. The closest I have found is for 88-93 GM trucks.

They look very similar, just clocked 1/3 counter clockwise. Swap pulleys and call it good?

If no near direct swap can be made, I can crack open a higher amp GM alternator that has a different fron half, and swap the MJ one over, but I would prefer to have an off the shelf alternator, to make replacement cut and dry.
 
Aside from the pulley, and it being clocked different(both are an easy fix), dimensionally they look to be the same. 105 Amp alternator from 88-93 GM trucks with the 454/7.4L


 
There was the stock 60/75A and and optional 105A available ... I just replaced the one on my 88 4.0L (uses the same GM CS-130 with the jeep clocking).
