Yeo the kit came whit 20 clips an in the middle it look like there goes a clip there is a hole on each side so am asuming there must be a clip
your saying there is a hole on each side of the center where a clip should be?.
then i would screw the clip on. if the pin is gone, and you have a hole thats all i can come up with, can you get a pic?
would make it soooo much easier to actually see.
