74 duster back seat removal

They can be aqravating. I think the deat back drops down some over time (gravity) and blocks the seat bottom from moving back far enough to release. Push the seat back up as far as it will go. Here's a tip...
cover those seat hooks in the floor with something, tuna cans and duct tape, whatever, because they will eat your knees up !!! Scar on my knee is no big deal. Scar on the wifes pretty knee is heart breaking.
