Can anyone tell me the purpose of the material that covers the hole on the C2 coupe rear window molding clip shown at left in the attached photo, which is missing from the clip on the right? That material is very brittle and I believe these clips are original NOS GM items, GM # 4871329. Should that material be pliable, rather than brittle?
Thanks,
Gary
