Not even bolting in an aftermerket set of seat could go easily as the mounts weren't even close to the original ones. The Corbeau seat mounts were about 4 inches narrower and about 4 inches longer than the originals. On the Right is a board I made with holes that match the Delorean floor. This acted as a template to keep the two rails in the right relationship to each other. Then I welded new bars in between the rails and extended the fronts.
