1975 Dodge Dart Sport vinal top trim help!!!

Thanks to all whom can help. I am trying to attach my vinal top trim. I ordered clips from R/T specialties. The problem I am having is getting the trim to snap down over the clips. I can snap the clips in place on the trim. Once the clips are in the trim it is impossible to put the clips over the welded pins that are in the roof. If I put the clips over the stud then try to slide trim over It wont sit flush to the roof and comes off easy. Any help is appreciated. See photos.
