X3300, please tell me. Are the upper and lower shock mounts exactly perpendicular to the swinging arm pivot axis, or do you allow for any misalignment with the rose joints?
I'm trying to do something similar with a 'twin shock-to -mono' arrangement and find that the available target area on the main frame loop is inboard of that on the swinging arm. The shock wants to point in towards the spine of the main frame, and is trying to twist the conventional rubber shock-mounting eyes. I suppose that rod-ends would allow for that?
I know it would be easier to find a mono frame, but where's the fun in that?
