I have a CG4 mount and I need to replace the two screws (or are they called bolts?), but they do not have any markings as to their size, and there is no information in the manual. I am going to venture a guess that they are all metric, but what do I know?
The first bolt has a large plastic knob and it is the main way to tighten the Vixen dovetail.
The second bolt is much smaller and has a metal thumbscrew end. I am not sure what is its main purpose other than hold the Vixen dovetail even tighter.
If somebody could tell me what thread size they are and how long they need to be. I don't have any fancy tools to measure threads and such.
I am attaching a picture.
