My '81 needs floor pan work and I have a body shop lined up to do the work. Passenger side needs to be replaced from toe board to rear foot well. I thought about the one piece panel from Camaro Central that includes the toe board area. Questions... has anyone used these and how do they fit? One drawl back is factory had two sections of metal with a seam between floor and toe board and using this one piece will not look factory. Should that be a concern?
