Here it is in-situ, thanks debolestis!

Although the piece works perfectly, there are a couple of things that other users might want to bear in :
1. I used a 2mm drill bit to widen the 2 screw holes on the bottom where DIN connector attaches. Without widening them the screws couldn't get in to begin biting into the nylon.
2. Because of the narrow hole through the neck of the piece, I had to tweak/arrange and carefully bend the cabling , including the grounding ring on the black wire (into a U shape), then push it all through very gently with a chopstick (high tech!). Finally, I bent the grounding ring back into it's flat shape and all was good with the world. Better to have the extra thickness on the neck though, just don't panic when you see it :)
