This is a cool old truck. It came to us with many issues; electrical, steering, and power. The truck was outfitted with a Ford 6.9l diesel and 4-speed manual transmission. We re-wired the whole truck with a Painless wiring harness. The drivetrain was updated with a newer 7.3l Ford diesel with a custom turbo setup on it.The radiator was upgraded with a Fluidyne aluminum radiator with twin Spal fans. We also upgraded the trans to a ZF 5-speed and threw a Gear-Vendor on the back of it for good highway cruiseability. The steering was upgraded with a Lee Manufacturing steering box and ram assist unit. These upgrades made a huge difference in the drivability of the truck. From downright scary to enjoyable.
