    Can anyone provide information regarding the original stock / factory supplied rear that would be found in a 2004 Dodge Ram 2500 4X4 5.9 HO with 6-spd (manual) trans.

    What do you want to know? Probably a AAM11.5 with 3.73 gears. if LSD, it will be a torsen style so the no friction modifier required. Recommended fluid is 75w90 or 80w90 full synthetic.

    It is the AAM 11.5 inch (14 bolt). I found MOPAR # 68149258AC covers for sale which claim to fit AAM 11.5 however for some reason everywhere I look it says this cover will not fit his truck??? Did they make different housing configurations of the AAM 11.5" rear?

    I think 04 had different axle company. Or was it just the manual transmission that was different in 06
