I need to make up some new spacers for a Bowdenex IFS front axle to fit between the two steel plates that connect the springs to the flame cut axle ends... there are five each side, four for the clamping bolts and one where the radius arm passes through. Thinking about the connection between the radius arm and the standard axle, this appears to be a transition fit (not loose like a clearance fit or tight like an interference fit). Does the radius arm actually rotate at all at the outboard end, or just pivot on the chassis ball? I'm trying to decide whether the spacers need to be carefully bored/ reamed to a fine tolerance or can just be tube with a more comfortable clearance, as the plates will provide locational restraint and the contact area between the plates and spacer may prove relatively small to stop it rotating if it really wanted to.
