They are on page 15-2 of the 1992 Dorman catalog, and cost in the range of $2 to $3. These clamps are plated steel but not galvanized, and seem to last reasonably well in the weather. They come packed one to a box with nuts, but I use them with plated washers and elastic stop nuts ("Nylock"). 73 de Dave, W6QHS
