Dave, I would advise taking some measurements first!.
Indeed Doug,
The challenge has not escaped me, although looking at this nice low image I think I can make it work
My approach was to ask the manufacturer for a drawing giving me the measurements & throw, ultimately this will allow me to mock up a dummy in CAD (Cardboard Aided Design).
I anticipate another one of my Blue Peter masterpieces on the horizon
