I know its not so difficult to remove 4 more bolts... but that were other of the reasons of installing the quick release (stock steering wheel was worn out)
I open the washer switch, and as I imagine, it can be made, but now I'm not sure about it... and I have to confirm the light/signal switch is about the same.. and find the pin wich when finally get out (about after 3 hrs) it get lost.
Its the cover with two half circles with a sprig (inside the half circles and the cover) that makes contact with the "gears" and all goes in the white long rod (from cover to end (switch)).
dremel... cut, make a hole in the rod insert something, glue or exposy, and/or try to melt it with a soldering iron and paint with krylon fusion
