Its not a difficult mod to make, in fact it is actually really easy to do, once you have the parts anyway, the hardest part was working out how it could be achieved and then working out how to fit the fabricated part so that it would sweep the full screen equidistant both sides and park exactly where I wanted it.
As for its effectiveness, it cleared the screen perfectly and fully with a watering can pouring onto it, and the difference in speed from the time it would take in comparison to both wipers I estimate at less than half a second with the stalk set at the first speed, virtually unnoticeable.
Combine that with a modern wiper arm with a stronger spring, slightly longer reach, and a hi-tec wiper blade I cant foresee any issues even in heavy rain.
The hardest part of doing it is drilling one 5mm hole, the rest of the fitting can be performed by anyone who can loosen and tighten a bolt!
, and the only thing that needs removed from the car is the two wiper arms , that's it.
If anyone wants to do it I can supply the kit, which includes the fabricated part, a modern straight wiper arm and blade, with the same diameter splined fitting as the Elan, and with stronger spring (which exerts a bit more pressure on the wiper blade) , and the all important instructions on how to fit it. I am not looking to make any money from it, only cover the cost of the parts and the time spent fabricating, and postage and im happy with that, 25 quid and a fiver postage. Remember as well, this mod changes nothing on the car, it can be reversed in a couple of minutes with no effect to anything.
Peter Stevens thought it was good enough for this....
Next mod on the list... A relocated steering and gear change setup with 1 seat in the middle.
