Do I cut the floorpan out of the 58 and put it in the 55? Do I replace the roof section of the 58 with the one from the 55? I know if I replace the roof I also have to replace the door pillar. I think I may have to get the 1955 media blasted first before I decide. I would love some suggestions from anyone who may have had a similar problem.
