Fastback Barracuda Folding Rear seats-damaged?

Lord knows I use it a lot with the canopy, chairs and cooler and such in the back going to car shows every other weekend in the late spring/summer and fall! It sure is nice when it works correctly! Always considered these cars one of the early crossovers there are so many of today! I have hauled all sorts of large items in the car back in the day! Always loved that fold down seat and rear hatch!
