I found an alternator from an '08 lmm, so I can set up dual alt's. Wondering if that is the same alternator as the 105 amp currently on my '04 lly? Obviously if I had part #'s off of the lmm alternator this would be easier, but those are not available until tomorrow. Provided his truck did not have the plow prep pack. on it, were the alternators still 105 amper's in 08?
