Tranny plate & clutch arm?

They seem to have changed the lenses when they started using the marker lamps as turn signals. The lenses used for turn signals have a depressed section in the center, the ones used as parking lamps until 50 have a domed shape as shown in the pic.

Do these have a Guide number on them? I think I have a pair I've been dragging around for the past 35 years, I may have just stumbled onto what they might be.....

The later ones used as turn signal lenses and running lights after about 50 or so are marked around the outside edge "GUIDE" and "DH-49". I don't believe the earlier ones are marked but I could be wrong.
