Howdy Y'all, I have been a member here for many years. I am 84 yrs old and am back working on my 2007 Duramax tow truck. It has an Isuzu engine I think it is a 7.3. Just wanted to say Howdy to everyone
probably the hard parts section under the appropriate engine model. if its the classic body style 07 then it would be under the LBZ. if it is the newer body style that came out mid year 07 and includes the particulate filter on the exhaust then it would be an LMM. if you get it wrong Tom, one of our excellent moderators, will move it for you
