Decided it was time to tackle the floor boards. One of the previous owners had tried to cover up the rust with fiberglass and body filler. Not pretty to say the least. Cut the passenger floor pan out and found that the cab mount was almost gone. Time to fabricate a new one.
Both bed corners needed some help, but the passenger side was almost gone. Made a new piece and got it in this weekend. Looks a lot better now. On to the passenger door and floor boards next. Later.
