Your 1971-76 GM full size convertible requires everything to be in proper condition for it to operate properly, if you are having problems with the rails not folding properly and hanging up this may be your problem. The number 3 bow has a plastic glide strip attached to the bottom of it that allows the side rails to slide over it when putting the top up and down, if this strip is missing the side rails will catch and not fold properly. Here is your opportunity to get a new #3 bow glide strip for your car.
