hello group, my daughter just acquired a 72 dodge dart swinger. does anybody know if the back glass rubber seal is the same one that fits a regular dart? the swinger has a curved glass on the ends, the regular dart does not. ebay has these seals available but states they fit both applications. does anybody know this to be true? I'd hate to buy one and find out it does not fit. also, is there an a biody group she could join? thanks again!
