How to remove MACH1 (spring loaded) gearbox. Instructions show two lock down screws on the back of the box. My 2.5 year old mach1 does not have those 2 screws.How do I remove it to inspect the worm?

I bought a new Mach1GTO in October 2017.  SN 10971. It has 2 screws in each motor box.

See the third photo in this set on IMGUR.  Also see my comment on IMGUR about needing a lot of torque to loosen those screws.
