Thanks for the pics.
Not tracking on a couple of things:
1) Grounding references...not sure why that mattered. As long as each wire going into the turret has a corresponding ring and plug, then it should work without any problem, right? Oh, I pulled open my Bulldog (intended recipient) last night, it looks like there are 6 wires going into the turret: 1 red/black pair (very thin) probably for the MG LED, 2 red and 1 black plus the antenna wire. Looks like I'll need six grooves.
2) You said there wasn't enough space in your Tiger for this ring. Is that because it's your El-Mod Tiger and has the extra electronics in it? Was the battery box in the way? (I thought you took it out of all of your builds.) How wide was the ring?
3) What were the springs for? I don't see them being used in the picture.
Thanks.
