Morning Mart, Best thing to do is take your old one into your local motor factors to get them to match it with what ever make they sell. Hope that helps.
I replaced my standard 16ins ones with 15ins and they are much better. They cover the area you want OK, hold better to the screen as shorter, seem (to me) to fit better as well as being a little easier in terms of not hitting the bottom seal so a good move. Jim
