In order to replace my Px rocker panel I’m going to dig in pretty deep. I may need to replace some floor supports. I think the book calls it a cross seal? In LMC I think it’s called cab floor support, # 9 under interior body support panels.
I could use more metal strips support pieces (that normally go around the edge of the floor panels but I don’t see anything like them. Mine are rusted off as they near the foot panel.
