On my 49 sub there is a spring loaded handle that sticks out under the side of the drivers seat. It engages into and out of 5 square punched holes in the seat track allowing you to adjust the seat forward or back. The seat track toward the passengers side also has these square punched holes. Is there some kind of device that is supposed to engage these holes also? Seems that I have seen somewhere a picture or a drawing that shows a cable and a pulley arrangement to engage these holes. Am I missing some adjuster parts? I only have the handle on the drivers side. Need advice and I think I came to the right place. Thanks in advance guys. Weeds
