Thanks, two were still in the head, one receiving the right front (shortest stud,) the other on the left rear (for one of the medium length studs.)
Locating dowel seems a wrong term, more like a locating sleeve? Hope I have the right critters in place.
Now I have the three larger copper washers, but the smaller one is AWOL. I wonder if there is a small furry animal in the yard that can't resist a magnet.
