Alternator issue

[ilikemud]

My truck is an 89 k5 it had a cs130 alternator. Swaped the motor and went with an aftermarket serp setup. My issue is the aftermarket set up is for a 10si alternator and I'd like to retain the cs130 but can't find one other than powermaster. Anyone know what vehicle had the cs130 with 180 mounts like the 10 si? Looking all over and coming up with nothing that works. Got one for a 93 Pontiac grAnd am has the 180 mounting but it is smaller than the 10si by about half an inch... Any help would be great.

Looks like ac delco part #1101292 will work with a pulley swap if anyone is interested. Comes on 88 thru 90 olds custom cruiser with a 5.0.

Did you actually install it? That would still be the 307 Olds then I believe...odd that it would fit.
