so some of you may know that my 01 2500 had an electrical problem and fried my alternator about 2 weeks ago, but now it seems my brother's truck got alternator envy and decided to fry that one as well.

My question is, if i buy an alternator, will it fit both trucks (one being a 97 12 valve, the other a 24v '01) or are they completely different? i heard someplace that they are different but looking at the napa site it seems both are the same amperage, and have the same number of grooves for the belt...

any insight is very much so appreciated! oh also, dad got a 99 24v today, is the alt for the 99 the same as the 01, or is that one different as well?

Why not just re-build the ones you have. Hell of a lot cheaper

oh uncle, thanks a lot! thats precisely what i've been looking for. actually i was thinking of buying one and then warrantying the other, seeing as how they're lifetime warranty and such
