Wind deflectors

[BruceB]

I am getting a couple of small bits of perspex cut at the moment to match my windscreen and to make small wind deflectors on either side of it. I have found this will cut down almost all the wind in the face when moving (I know this is one of the joys of Ribbing but not when 50% of the wind is liquid)
I am looking for some sort of hinge to mount them onto the side of the perspex sceen. I have been looking at the sort of hinge used on kit cars but they seem very expensive, probably because the companies make money on the "extras" you need to complete rather than the kit.
Has anybody seen anything likely that I can see online and buy if OK? The deflectors are quite small, only 22cm x 5cm as I found that was all that was required.
