Davia,
Source the sprocket adapter locally. A clever fellow in a machine shop with Solidworks or other CAD CAM design software could have it designed and machined in minutes. There is a lady near me who is the proprietor of MBrebel.

All her sprockets and sprocket adapters are CNC machines locally.
