seems like they flex great, about the same as the 40 year old ones!

worked as they should

only needed a few for broken replacements.

Very good. Replaced the old clips. Everything is nice and tidy again

.Clips worked great and door panel is secure . . . Had a 1971 back in early 80s and couldnt find any parts for it then . . . Today, I own a '72 vert and WCCC makes owning that Cougar a lot less painful when you need parts for this low production car.
