1. Using a Philips screwdriver, remove the four (4) screws with washers
running through the seat frames (C1113) and into the seat back (P2588).
Older models you will need a 7/16” wrench or socket to remove the bolts

use a larger hardware size. The holes in the seat frames on the older
models may need to be slightly opened up with a drill to install the new
mounting hardware.
