Just bought first Duramax, 2004 4x4, how do I tell lb7 or lly motor? Also I cant get the miidle front seat to fold down, can somebody help me out with a fix?? Thanks, John
I have already forgotten how to get the seat down....I think there is a latch. LLY or LB7 one of the digits of the vin will tell you that, I don't remember which one but I'm sure somebody will come along and help.
