1866yellowboy,
I had the same problem with my 1949 3100. The mounts for the front are a flat plate with a protrusion for the shock link eye and bushing to mount the shock link. Don't have a photo of these on hand just now as my truck is in a garage a ways from the house. I found my by placing an ad in the "Truck Parts Wanted Section" of the forum and got GREAT response. Had a member send me the complete shock and mounting assembly for each side and all I had to pay was the shipping. You might give that a try. By the way, there is no spacer between the mount and the spring perch.
