1992 Camaro Z28:

How do I put the Upper Roof Rail Molding (Black plastic strip above door and down the windshield) back on?

My alarm shop installed the antenna for the alarm and ran the wires under it. He removed it and didn't hook one of the white clips I can see under the weather stripping at the top. Seems to be a white hook that you slide over to lock the Roof Rail to the car? But I don't see how you can do that since your finger can fit in there..

Thanks
