45 Truck parking brake problems

Per Rich B's comment, I went out and looked at my backing plates. The place where the cable threads through the backing plate is bolted on, so it seems that there is that difference between my backing plates and Rich's. Pic attached.

The linings, while worn, seem to have a lot of meat on them. The drums may be a little thin. A friend checked them today and said that they were worn. I want to get a second opinion.
