Repair the passenger side (right) center-rear rail with this Rust Buster 33.40-inch cap for Standard / Regular Cab K10 and K20 trucks with an 8-foot bed. The section covers the area from ahead of the forward leaf spring mount to ahead of the rear cab mount. Heavy-duty 7-gauge steel, factory-aligned holes, and knockout tabs accommodate installation while retaining the original rivets. Welding is required, and Rust Buster backs the section with its lifetime warranty.
