my 1950 coupe's front drivers side seat back doesn't stay up when you sit in the driver's seat. It lays back more than it should. Is there a bracket or a piece of hardware missing?
The passenger side seems to be fine...
On the bottom outside corner of the seat there is a rubber wedge (seat back stop) screwed to the seat frame. If it is not there the seat will go too far back. They are hidden by the seat cover. I had attached a couple of photos of the seats before and after I redid them that shows the black rubber wedge and the location. I found a picture of a white set on e-bay.
