Well, I got a spare front controls (with the controls) bar coming from Pinwall cycle & it should be in sometime next week. Thanks Paul for the guidance to the Ebay listing. I had been browsing Ebay & not finding one listed until I was able to dial in my search re: Speedmaster/Bonneville.

Since the spare comes with the controls (including the clutch rod) I'll be lengthining the clutch rod via my own mod. I'm thinking a bit of SS tube, cut to the required lenght to reach the new control set-up (with a bit extra length to add strength to the span) & welded round the joint on either side to the spare clutch rod I'll have will work fine.
