Interior help with lost part.

Thanks for the information. I will try a license plate snap plastic deal and your 1/2 pvc pipe idea and think that will work ok. I do appreciate all the ideas .
I could start a new thread or search again to find the plastic guides or options on the side windows. I am not 100% on what there called. They have grooves and held onto the window by white t type snap hardware. Have a black weatherstripping and chrome color plastic I assume it is to seal the window tight in the weather strip as well as help hold seal in the end window guides. I have purchased a original parts manual in hopes to give me a better idea of names and placement of parts on the car. I have looked at other years to see if there is anything I could use for this instead since I am sure I cannot buy them. Had no luck
