Re: Registration says 2007, VIN says 2006

2007 classic T800 was an odd model. There are more than a few parts that are specific to that year truck.

Look at the compliance sticker on the LH doorjamb or door for the actual build date... MM/YY.
Usually a model year runs from August of the year prior to July of the actual stated model year. August - December 2004 and January to July 2005 builds were 2005 model year. My 2005 was September 2004 build IIRC.

2007 was really weird since, I believe, they built T800 and T900 trucks from August 2006 through at least May of 2007. I might be wrong about the start of T900 production... it might've been delayed somewhat and the T800 might've been built right through July.
Keith Seymore might be able to say since he worked at GM in that timeframe.

RTFM... GM Parts Books, GM Schematics, GM service manuals, and GM training materials...Please include at least the year and model in your threads. It'll be easier to answer your questions.
And please let us know if and how your repairs were successful.
