I'm just going have to start tagging all my pictures.
The truck is a 70 K20 CST former bucket seat truck. The driveline is a typical 350/4-speed/NP205. However a Gear Vendors O/D is mounted to the transfer case rear output but it can only be used in 2wd.
Looked at the truck myself but a new member Nomad74 up in Northern California bought it and had it shipped up. Turned out to have a flat cam and so he redid the top end. Last I heard he was installing the saddle interior parts the PO supplied with the truck and intended to paint it a similar but not stock color. Shortly after that (a year ago) he dropped off the boards.
