is the difference between the 2007 and 2007.5 just body and dpf or is there other stuff? I was under the impression I bought a 2007.5 as it was new body . Am I wrong?

 

Early 07s are the LBZ generation motor which had no DPF. I believe it was offered in classic and new body style.
07.5s are LMM generation which had a DPF and the new body style.

There's probably something I left out.

 

LBZ's were ONLY in the classic body, NBS will be LMM only

if you have a new bodied 07, then you have an LMM, dpf, intake throttle body, and all that fun junk
