1966 C30 BODY SWAP — SHORTENING THE RAM FRAME

Getting the 1966 C30 cab and box to sit right on the 2004 Ram chassis meant changing the wheelbase.

We shortened the frame down to 127 inches by plasma cutting the chassis, removing 13 inches, then sliding the frame section back into the existing frame channel.

Once everything was measured, squared and positioned correctly, the frame was welded back together and reinforced to lock the new wheelbase in.

A lot more involved than just dropping an old body onto a newer chassis — everything has to land where it belongs.

Next step: getting the cab and box sitting exactly where we want them.

OLD BLUE BUILD 🔵🛠️

1966 GMC C30 body ➡️ 2004 Ram 2500 Cummins chassis.

PART 1: Getting the old GMC body fitted and sitting right on the Dodge frame.

A lot more goes into a body swap like this than just dropping the cab on and bolting it down. Mounting, positioning, clearances and getting the proportions right before we move onto the next stage.

This one is going to be wild when it’s finished. 👀

Follow the build — OLD BLUE is officially underway.

🔥 Putting the power to the pavement. 🔥

This killer 1968 Camaro came into the shop for a Yukon Posi upgrade, making sure both tires hook when those twin turbos come alive. 💨💨

With a twin turbo LS under the hood, traction is just as important as horsepower. The new Yukon Posi gives this beast the grip and reliability it needs to handle serious power.

Another awesome build getting one step closer to hitting the streets. 👊
