This GMC C/K 1973-1991 got away, but there are more like it here.

This 1978 GMC Sierra K15 is a half-ton stepside pickup that was acquired by the seller in 2017 and underwent a subsequent refurbishment that included refinishing the body in black and replacing the wood slat bed floor. Power is from a replacement 350ci V8 mated to a three-speed automatic transmission and a dual-range transfer case. Features include 15″ alloy wheels, Bilstein shocks, chrome-finished bumpers, LED taillights, a Flowmaster exhaust system, low-back bucket seats, Vintage Air climate control, a JVC CD stereo, and a center console with an integrated cooler. Additional work performed under current ownership is said to have involved overhauling the suspension and steering along with replacement of the brake master cylinder, body mounts, and rear wiring harness. This K15 is offered in Florida with a clean Alaska title in the seller’s name.
