'02 Duramax...Battery light came on and gauge shows discharge. Occasionally it will charge normally for a day or two then shows discharge again. Time for a new alternator I guess. My question is, they show two alternators... a 105 amp and a 130 amp. I don't know which one I have and would like to have the larger one. The salesman said they were different sizes. Can I use either or do I have to pull it off first and walk to the parts house? lol...help!

Use your VIN# to do a parts lookup on a GM based website, such as GMPARTSGIANT. You will get the parts available for your specific truck. Having the correct GM part number, you can search for best price, best service, best availability, etc.
