Hi Kenny,
Here are dimensions from my 55 first series striker shims. Thickness 0.170 inch. Width 0.810 inch. Length 1.420 inch. Sorry about the silly units of measure. I am definitely metrically challenged.
If you scroll back a few photos on Brad's Flikr site you can see one side of the shims is serrated horizontally. The other side is serrated in the center 1/2 inch in the vertical plane to match up with indexing ridges. Anything else just ask.
Brad, the NOS stuff you come up with is just amazing.
