2 flashers in my scamp.....?

First there was a metal bracket on the right side of the ash tray hanger that the signal flasher sat in. If you remove the ash tray you should see a tiny limb of this metal clip. Then later models had a all plastic flasher with a rectangular nub cast on its top. The metal clip was deleted. They poked the nub through a square opening in the same location and rotated the flasher 90 degrees to attach it. So with the ash tray removed you just might see a little bit of plastic showing on the right side of the hanger.
If you have factory a/c its probably best to remove the glove box liner to get there. I have removed the 4 screws from the ash tray hanger and fiddled it around sideways enough to get at the flasher, then coaxed it back in place again. That was with aftermarket knee knocker a/c in the way. And the radio support was in the way of fiddling the ash tray hanger around but I goter done.
