Anyone know what the function of the thin cable and pully system is on the bottom of the bench seat frame?
It's The Adjuster On some years.... other years GM stupidly ran a rod across the middle of the storage space where toolboxes & axes , crowbars etc. soon ripped the rubber center support out of the floor , disabling it....
Thats the doohickey that rattles againts the botto of the seat frame and drives the driver nuts. It was a no charge factory option only in the deluxe cab models.
Ya wanna know how to replace the cable so that you can adjust your seat? Click on this link http://chevy.tocmp.com/shop/1948_51truck/51ctsm0116.htm Simple, huh?
