Where do I buy these window trim clips?

I used stainless ones. Its worth looking into
What would be the need for stainless?
Yep there are 2 different ones. Got new ones and used ones from my 69 Dart. I’ll send what I had left, prolly not enough for 3 cars so use what you can. I don’t intend to do another. Got the new ones from R/T Specialties couple years ago. So good luck on your project.
