I have 2 sets of inner door panels one set from a 39 and the other from a 41. I noticed that the panels from 39 have one screw hole on the top edge that covers the gap by the window. The 41 panels do not have a screw hole on the top edge. Can any one tell me what that screw hole 0n the 39 is there for.

thank you,
