Go to www.pa-performance.com and take a browse. Their 2G 95A alterntor bolts on with only minor wiring upgrades and is a nice upgrade from the stock 65A unit. I'd recommend the 4ga. cable upgrade to go with it. If you need more than, get their 3G 130A. 15 minutes with a Dremel tool and a burr will remove enough material from the alternator bracket to allow it to then bolt-on. I went 95A first. But when I added two big electric cooling fans and seriously upgraded headlights, I was taxing it at idle at night with the a/c on. So I recently put the 130A on. No problemo.
