Clever stuff. Reminded me that many years ago I helped a mate re-make his mark 1 Ford Cortina. We were about 18 at the time and he was an apprentice motor fitter. Amongst other things he decided that he wanted electric windows. After doing a bit of research he got hold of 4 Triumph Stag window mechanisms froma local breaker and proceeded to re-make them in a similar manner to the wiper mechanism that these guys did. I was really impressed by his ingenuity and fabrication skills. When the car was finished he was the coolest dude in town with 4 power windows, in a Cortina, in 1976.....
There are some very clever and skillful people around and I take my hat off to all of them.
