Shortening the center of the chassis is substantially more involved. The frame needs to be literally cut in half, 1 foot removed, and the front and rear frame sections welded back together. In other words, it's not a project for the faint of heart. Alignment of the frame sections is also a critical procedure, and failure to do so properly could mean the difference between a sweet shortbed chassis and a pile of junk. After the frame is fixed on a level floor using jackstands, the cab mount bolts are removed to allow the cab to be raised up from the frame for clearance (inset). All of the plumbing and the wiring need to be removed before the frame can be cut.
