1967 vs 1968 windshield trim

HELP..... I have a 67 Dart that I do not have the trim or gasket to install the windshield. I do have 68 trim and clips. I would like to know how others have handled the installation? Also, how is the large gap at the ends of the dash and the windshield pillers handled? Any help would be greatly appreciated.

Thanks
