I paid 600.00 a year or so ago to have a new window sewn into my top. Made a huge differerence as it is bright and clear. I did not have the cash for a new top at the time and my original top was in OK condition. Now I wish I would have sprung for a new top with a glass window. Even though I like the large clear plastic window, it is a huge pain to get out to do the chop when I am putting the top down.
