What is the 1967-1972 Chevrolet C10 Cab corners, floor pans and rocker panels rust out at the cab mounts?
The 67-72 C10 cab is a rust trap. The box-section cab supports run from the body mounts to the inner rockers and are spot-welded to both the inner rocker and the floor, so when the rockers and cab corners pack with debris and moisture (the rockers are literally cup-shaped pockets… Repairs typically run $800-$6,000.

What is the 1967-1970 Chevrolet C10 Four-wheel drum brakes (1967-1970) fade and pull?
1967-1970 C10s used four-wheel drum brakes on a single-circuit-feel system that is marginal by modern standards.

Combined with 50-year-old brittle wiring, dirty bulkhead connectors, and breaker-point/co… Repairs typically run $200-$900. Severity: medium.
What is the 1967-1972 Chevrolet C10 Worn rear trailing-arm and front control-arm bushings cause float and rear steer?
Unlike the 3/4-ton trucks, the half-ton C10 2WD uses a coil-spring rear located by two long (~57 inch) trailing arms plus a panhard bar/track bar. The big rubber trailing-arm bushings (and the front upper/lower control-arm bushings and ball joints) perish with age, letting the re… Repairs typically run $200-$1,200. Severity: medium.
What is the 1967-1972 Chevrolet C10 Worn steering box and front-end linkage cause vague, wandering steering?
After 50+ years the factory Saginaw recirculating-ball steering box develops slop in the worm/sector, and combined with worn idler arm, tie-rod ends, drag link and ball joints the C10 develops the classic 'wandering' feel where you're constantly correcting and the truck darts on… Repairs typically run $250-$1,500. Severity: medium.
