The 997 RSR (later version) uses a forged AL LCA with a replaceable bearing & pin on the upright end. What I would like to understand is why the pin is available in 3 different lengths?
Has anyone tried machining a non rsr arm out to accept the outer monoball?

tricky to clamp the arm for milling I guess .
