You might want to try one from a '98 5.9 Grand. It is 136 amps, and should bolt to your existing brackets. Another option is the one from any v-8 Grand, they are about 115 amps. The problem that you may run into is setting false codes for charging, and leaving your "check engine" light on all the time. The p.c.m. senses both charging voltage and the alternator field circuit. You should probably stick with the ND, so this won't happen.
