Bought the replacement plastic seat belt covers that go over the seat belt slits in the headliner. I am having problems figuring out which piece snaps into which side (left vs right). I tried to attach both ways last weekend, but it seemed to be taking quite of bit of effort to get it to snap up, so I stopped. Anyone have any pictures or can explain clearly how I should go about getting these pieces to snap up there without breaking them or the plastic seatbelt piece?

Thanks,
Jeff

It should be fairly easy to tell right from left, the problem is getting the headliner material out of the way for them to properly seat. Are the slits on the back or on the sides?
