Broken linky. I'm in no huge hurry. Finally riding more than working on bikes so whenever you get a pic is when you get it.Just noticed the thread from the bump, I have a plastic housing '81 GS550E 7" round, pretty much the same thing a N model Suzuki comes with in the 90's. Should be nearly identical to the B12's sizing.
I can dig up a pic of it soon if your not in too much of a hurry.
(Looks exactly like this^^. Slightly faded on the black part, could clean up well though.)
