66 dart top help

Been putting a 66 Dart together and getting close to finishing it. Was wondering if anyone has some info on the channel that the weather strip on the top's header attaches to. Mine was missing and finding anything has been a needle in a haystack. The pic is a older one but I'll to put some newer ones together.

those pieces are either good on your car or toast (mine was) it's a simple C style channel but it has compound curves in it to match the header
