If no one provides the exact measurements then you can try to experiment. The plates to jack the rear end up are essentially triangles with the position of the two front holes dictated by the hole for the front of seat pivot and the sidecar hole. You could then put a series of holes going backwards at, say, one inch intervals to take the top mount of the AVO. You could then try the handling by using the various holes until you found the one which gives you the best result.
