Hi Craig.? Are you planning on a tucked motor/spring-loaded worm upgrade as well?? If not, you can just get the Gemini retrofit kit and install it yourself (this is what I did many years ago on my G11).? But keep in mind the cost of a brand new GM8 with everything mentioned is $2145 (mount head only).? The Gemini retrofit is $1595, and I suspect the tucked motor/spring-loaded worm upgrade in addition would put you well over the cost of a brand new mount.? Food for thought.
