Saw your other post...just don't know the answer. Generally these cushions and side coming panels are attached with threaded studs that stick through the fiberglass gunnel. Look for Hex nuts under the gunnel. Helps to stick your cameral phone back there and take pictures so you can see places your head won't fit.
You don't need to be too concerned about which thread you post in, because us regulars see all the new posts by scanning through "View Active Topics"
