The inner wheelhousing is clamped to the framerail and seat bulkhead, the floor drops are clamped to the inner wheelhousing and trunk floor, and the trunk floor is clamped to the inner valance, which is clamped to the end of the framerails. Remember, the whole floorpan assembly is bolted to the body jig. The reason for clamping everything in place, rather than welding one piece at a time, is to correct any misalignments and trim excess metal if and where needed. Once everything is fitted together, the welding will begin.
