i have a 98 jeep cherokee my 90 amp alt went bad on me the other day well i work at advanceauto parts so can some one just tell me which grand cherokee alt will fit. I know ill have to grind the mounting plate a little and do i grind on the engine or the alternator. also i would like to know the exact year and engine of the grand cherokee alternator so i know i get the right one and what amp its suppose to be i think it is 136.

I'm wondering the same thing as far as where to grind, but yeah I believe it's a mid-late '90's V8 ZJ application that you want. Your computers at work should specify which years use the same alt and what amperage it puts out.

Guys - the alternator you want for a NON-RENIX swap is a Denso 7913. If you have a Renix this swap WILL NOT WORK due to the different regulator configuration on the Renix.

Also not pictured is some grinding on the side of the timing cover but it is minimal.
