Collapsed Seat-backs 64 Barracuda

There's no easy fix, if it's in the seat frames. If it's a frame problem the seats have to come out & be disassembled. The welded pin that forms the latch can be bent, the frames can rust badly if repeatedly soaked through the foam. They usually can be fixed though, just clip the hog rings carefully after separating the seat halves. The metal can be straightened w a hammer & dolly, and a straight piece of 16 ga metal can be pad welded over it if there's a crease or crack.
