1990 JEEP CHEROKEE LIMITED 6 CYL 4.0L

I just bought this hoopty and it has a bad alternator, the parts store says it could be three different sizes.. 100 amp , 85 amp or a 61 amp. The jeep has power seats, windows and trany control. how can i tell which alternator I need or dose it matter ?

any help would be appreciated

the more amperage the better with all the draw from the options

Get the 100, power options drain more. Plus as an avid jeeper, more power is always better.

the 100 would be the way to go

Go big! If You end up adding stuff (lights winch cb etc,) you'll be glad You did.
