Thanks El D, but it doesn't have a dove tail slot, it has a flat bar screwed on the side with a slot in it to adjust the elevation, and the sight was just a round bar, with a V groove in it, that was screwed to the sliding bar on the side. You adjusted the windage with the screw. I have used the screw cap from a spark plug once and it it worked, ok, but I would like to put the original sights on it. It needs to be completely rebuilt on the inside. All the gaskets, and seals, are dried, and or rotted, and are no good.
