Though aligning the body on your bump side may seem like the most basic thing on a build, doing so is often forgotten but relatively easy to address, even after you are “done” with your build. Body alignment can make an average build look nicer, or a nicer build look average. The biggest mistake you can make is aligning the body parts in the wrong order, making it a more challenging task.
So, where should you start? The doors. You start with the doors because their correct position is solely based on the cab, which is not adjustable. The cab is the solid foundation that the doors, fenders, and hood must fit. The fender location is determined by aligning the “bump” line to the door, so if the door is off, the fender will also be.
Misaligned panels can adversely affect many parts of the truck, including faulty door and hood latches and proper sealing of weatherstripping and trim alignment. When aligning body panels, you must let the lines tell you what adjustments are needed. Your eye is the best tool for this because if the panels are not looking right, they probably need more adjustment. So now, on to the fun part.
