Ahhhh!! Now I get it!! Well I do but of course I'm no help 'cos we drive on the correct side of the road over here in Blighty and wouldn't be able to drive very far or fast with one of those on the right side. [emoji4]
Again, all I can offer is if you cannot find one online, draw something up and take that photo along to your local welder fabricator and have something made up.
Just one question…
Why?? (Ok I lied about getting it!!)
