Tim ..I saw the Jim Carter tech pics and they both appear to be for TF pickups - I've got one of each of those carriers. The 1/2 ton TF side carrier has one arm actually go through a hole in the fender.
Now I noteice I missing the bottom reinforcing bracket for my TF carrier as well..looks fairly easy to fab up tho.
Interesting on the spring spacer. Neat idea. I wonder how thick it was.
