you will need some glue because it's broken.
there should be a peg or tab, whatever you want to call it, at that end.
they are $63 from tasca pn 6R3Z-6321453-A for lt side
I just went and looked at it. It's there but broken. I managed to get it back in the hole but it doesn't look like it will stay very long without some adhesive of some type. Thank. I will probably buy it.
