Nice easy one for a Wednesday morning....
Recently fitted new wiper blades to my GT, bought from Half frauds.
They didn't have the ones with the spoiler on the big blade, like the original fitment, so I bought the standard ones, cos I really needed new blades.
They squealed like a stuck pig, especially when the auto wipers went into hyperdrive for no reason at all (another story)
I put up with them for 4 months, but enough is enough, bought some proper alfa ones with the spoiler online.
Here is the problem....Not having anything to copy, does the spoiler go on the top of the blade or the bottom? It fits both ways up.
And why? (not an essential question, just a curious engineer)
