Recently picked up a 2005 Chevy 2500hd Ext cab etc etc and all the fun jazz. I got a pretty good deal on it except for the fact that it currenty has the 6.0 gas engine in it. A friend of mine has An LB7 out of an 02. I can pick it up for a pretty fair price but I don't know if anything was different, installation wise, from the LB7 to the LLY, and what would be needed. I'm new to the forum so I hope I posted in the right spot. Thanks in advanced!
