This is a 40-year-old truck, not a showroom restoration. It has normal cosmetic wear, but it's a solid, rust-free square body with a substantial amount of money invested in the drivetrain and mechanical upgrades. Most of the truck has been rebuilt.
Great-looking stance, classic square-body styling, and plenty of big-block attitude. $19,500 OBO
Serious inquiries only. Message me for more information or additional pictures and videos. Not interested in trades.
What the photos show
- The only photo is a side profile of the gray stepside.
- Paint looks even and satin rather than glossy; the body reads straight and tidy.
- The interior beyond what's visible, the engine bay and the underside can't be judged from this single photo.
Money: At $19,500 the photo shows a clean, mild-custom square-body; the money rides on cab rust and the drivetrain, which the gravel side shot doesn't show.
