1970 GMC C15/C1500 Suburban GM 8.5 Inch 10-Bolt Chassis and Suspension Parts

GM’s 10-bolt rear axle has been around since the 1960s, here’s how to determine if your junkyard find is worth taking home

It's alive! Our 1968 C10 truck project is one step closer to our first drive. In this episode, our old truck finally comes to life with a cammed junkyard LS.

In Episode 3 of our C10 build, we install a front suspension kit and finally have a rolling chassis!

In Episode 2 of our '68 C10 build, we rip it apart, clean up 54 years of rust and dirt, and get to work on the rear suspension.

In this episode of our '68 C10 project, we hit a couple big milestones. The engine goes in and we hit our first car show. It may be just a rolling chassis, but we're mighty proud of how far we've come.

Now that our '68 C10 cab is straight and rust-free, it's time to bolt on the rest of the sheet metal, get it straight, and get it painted!
