1973 Scamp headlight switch

I had the same problem.. the one they ordered for me went in just fine, but then the shaft couldn't go in far enough to "click" in place. The shaft went in the new one almost an inch further than the old one, so the old one went back in. I guess I'll have to live with the dash lights flickering from time to time. If anyone finds a reliable source for the headlight switch, I need one too!!
