The new turn signal switch arrived this week. The contacts on mine were getting worn. There is a guy who rebuilds them, but he won't work on the "old" '56 and older switches. He only works on the "new" '57 to '60 version. Fortunately new OEM switches are available. It's the same switch used in VWs of the era, so there is still an adequate market to keep making them.
There is something in this cancelling mechanism that the rebuilder doesn't like. The old one looks more robust to me.
My painter warned me of this, and I’ll pass it along. Some microfiber cleaning rags have nylon or some other hard thread in the binding. He recommends cutting the binding off before you use them on paint to keep from scratching it. I checked and these cloths from Autozone had the abrasive binding. Cloths I got from Wal-Mart didn’t have any binding at all. I thought that made them cheap, but no, it made them safer.
