Thanks Frank,
It really helps to know others did the same as I'm planning to do .... With trepidation, I tread the same path ! (Dremmel in one hand, and small flat chisel n the other).
Does the plug - jack connection look normal ?
(Is this a stereo jack or something ?)
I bell'ed out a mono plug connection and apart from the amount of 'plug' hanging out of the sock, I'm good to go with this ...
