I've failed to find a 13 beam type blade here in the US. I don't know if something of the design of the beam needs a longer wiper blade, or just the scarcity of cars requiring 13 blades now days but after using them on my daily driver cars, I'd love to find one for my P car. The shortest I've seen here stateside off the shelf is 16 inch.
I was able to Google a place in the UK that's got them Vision X brand, but I'd rather not have to order a wiper blade internationally!
Wiperblades4U Perhaps a new product for our host to look into?
