Restoring a postwar Chevrolet half-ton pickup
The postwar Chevrolet pickups, the generation with the split windshield and the deep, rounded cab, are among the easiest old vehicles to get back on the road. They were built in enormous numbers, they were built simply, and almost everything that wears out is either still made or still turns up at swap meets. What stops most projects is not the mechanical work. It is starting the bodywork without a plan.
Decide what the truck is for
Before a single bolt comes out, decide whether you are building a driver or a show truck, because the two jobs diverge almost immediately. A driver can keep its old paint, its honest dents and its patched floor, and the money goes into brakes, steering, wiring and a seat you can sit on for an afternoon. A show truck means the cab comes off the frame, everything gets stripped to bare metal, and the project stretches over seasons. Trucks that get finished are usually the ones whose owner answered this question honestly at the start.
Where they rust
Look in the same places on every one of these trucks. The cab corners behind the doors rot from the inside out, and so do the rocker panels, the toe boards and the floor under the pedals. The bottoms of the doors go, along with the inner and outer running board brackets. The bed sides rust along the bottom seam, the wheel arches go thin, and the cross sills under the bed wood rust where water sat in them for decades. Lift the bed wood and the mats, poke everything with a screwdriver, and take the measure of the truck before you buy parts.
Patch panels or full panels
Patch panels are sold for all the usual rot spots, and they are the right answer when the surrounding metal is sound. The trap is using a small patch to avoid facing a bad corner: you end up with a seam in the middle of thin metal and it will telegraph through the paint. If the whole lower corner is soft, buy the full corner. Cut back to metal you can weld to, butt weld rather than lap weld where you can, keep the heat down, and plan the order of the panels so each one has something solid to line up against.
A dolly makes the bodywork possible
A cab on the floor is awkward, heavy and easy to distort. A simple wheeled dolly built from square tube, supporting the cab at the original mounting points, lets you turn it, get underneath it and roll it out of the way. Support the cab where the factory did and nowhere else, or you will pull the door gaps out while you are welding.
What to do while the cab is off
With the cab away from the frame the mechanical work is suddenly pleasant. Renew the brake lines and hoses, the fuel line, the shackle bushings and the steering box seals. Clean and paint the frame. Replace the wiring harness rather than repairing it, and take photographs of every connection before it comes apart. Bed wood and the metal strips that hold it down go in last, after the bed is painted, and they need to go in unstressed so the bed sides stay parallel.
Keep the truck a truck
These pickups are pleasant to drive slowly and honest about what they are. Modern brakes and a better seat make one usable without hiding its age, and a truck with its original patina and sound running gear gets more conversation at a show than a glossy one. Whatever you decide, keep the parts you take off, label them, and write down what you did. The next owner, or you in a decade, will be grateful.
