Throw out bearing question

This is from the MP chassis manual. It's a jig without any direction on how to use...…..

The .310" dimension I relate to the disc thickness. Evidently the finger tops should come out to the 1.700" dimension when this is between the pressure plate and flywheel bolted together. I had a .310" plate made from an old 3/8" ram spacer. I use a depth mic between two fingers at a time measuring down to the plate. I imagine one could get real close with just some quality 5/16" flat stock.

On this new pressure plate I found one finger .050" short using this. The nut on the right was adjusted. A good eye can spot the extra peens. The other two were right there.
