You should see a slot milled into the worm wheel cover. Appears to be clear Lucite 0.100" thick and
extends 1/2" above worm wheel cover and 0.700" long. It has a thin vertical scribe line on both sides.

Thanks for the photo, Don. That clear plastic piece is missing on my mount.
Hmmm, wonder where to find one?
