My 9' GCI has these parts i believe calld rail blind extrusions. In the picture you can see the original one screwed to the inside of the apron. This rides up into a rail groove and with cantilevered force and a small lip, holds them up to the rail. I am missing 2 middle ones on the long aprons and one middle one on the foot apron. There are two screw holes on the top edge and inside face of the apron. I purchased some of the smaller pieces but they do not fit. I am looking for 5 of the original style to fill in my missing ones since the holes are already drilled on the apron. Can someone shed some light on this issue and maybe I can learn a little more about this part.
Thanks
Randy
