Right side vintage sidecar for 47 Vincent Rapide

I am wanting to mount a vintage, enclosed, hopefully British type, side car to a series B or C twin Vincent.
Looking for sources, advice to make this happen.
I need left hand kick mechanicals for twin, altho i do have Grosset electric available.
I am pursuing Overlander OZ.
How would a Comet kick lever handle right hand sidecar mount?
Is there a UK/USA side car newsletter, vendor, club, forum, etc.
Has anyone done this vintage righthand vintage sidecar?

I would like period type wire wheel, suspension with shock absorber, non fiberglass style body.
I am smitten with Busmar Astral series, but nautical style of period bodies as well.
Watsonian, Blacknell, Garrad, Noxal, Swallow, Busmar.
Thank you
