Are the Britpart ones designed to go on the Disco 2 too? So no "key spline"? Can you pop them apart and twist to correct angle and reconnect? Cannot remember how many splines there are but should be easy enough to calculate angle from number of splines twisted.
No idea. I haven't popped it apart either. I'm sending it back so don't want to damage it. They're not right out of the box though.
