Robert B,
I have an extra one of the small flat metal piece depicted in the link that olezippi provided above. It has the curved serrated edge. You will need a spring as shown, as well as small carriage bolts for the hinges (these can be obtained at the Filling Station). I can also take a picture of my truck from underneath the dash, which will, hopefully, show how it goes together. I will post more later today.
