I have a hard top T. I bought Kirbans door and window seals. It took three attempts to get the window to seal properly. I felt that the seals could have been a little softer, they are pretty firm and unforgiving. The window has to be perfect for it to seal properly, at least on my car. I also bought their window rattle kits and Serio's book. Also, new pins and busings in the hinges. I have more time than I would care to admit in these doors and windows. They are crank windows on my car. With all the time and money I have invested into these windows I'm fairly disappointed in the results. Is it the seals? partly IMO. Should I have to devote my life to becoming a door and window expert? It looks that way. Whatever you buy, be prepared to spend an incredible amount of time getting them right. After you are satisfied with the results you to can become a Regal door and window expert! Maybe we can tour the country and give clinics! Drew
