Well, I'm into it. Pulled the truck into the cleaned-out garage yesterday, and began the dis-assembly. A lot of prep work had to be done before hand...

Had originally planned to let a Duramax enthusiast (GM mechanic) I've known since about 2007 do the work, but it didn't work out. As complex a project as this is, and being hard to please, it's best if I do it anyway - for a variety of reasons (some shocking and some, well, just because). More later...

Onward and upward!
