Mine has 16" blades on and I believe the standard is 13". 16s are too long and bang against the rubber seal but going down 3" seems a lot. Are 14" or 15" blades any better if available or does the stock size work well?
I can't have had my gleases on when I measured them. They are just shy of 14" so I've bought some 13s and moved the drivers side further round on the spline to see if it stops bashing the window seal.
