Sportster frame guru needed

[Kevin Mahoney]

I sell the Cozy sidecar. I get a lot of requests from Sportster owners about mounting the sidecar to a Sportster. A customer sent me some pictures which include standard parts and one fabricated part.
I wonder how many models of Sportsters they might fit? Is there anyone here that can give me a hand?
I have lots of pictures.
