Starter issue?

Before adding shims:
- might need a helper
- disconnect [+] batt cable at the battery
- run a jumper from the batt [+] terminal to the sol terminal on the starter. This will push the pinion gear out so you can check for engagement. As long as the the Bendix unit does not contact the back of the ring gear teeth, I see no reason for any shims.
