I have a 1931 Sloper the rear sidecar fixing seems to be standard fitting on these machines its a stub fixed in the rear part of the frame , does anyone know if its possible to unscrew this so I can fit a standard cub and ball sidecar fitting or is there a side car fitting made that will fit in place of the cup and ball I have with my sidecar
I can see all bikes seem to have this fixing so I am sure it would be able to fit a watsonan Side car chassis to a BSA ?
