    i created my spacer from 1/2" thick HDPE (high density poly ethelene platic sheet)

    2" ID 4" OD 3" bolt circle of (6) .25" holes
    (i think the thing is really metric so the bolt circle should be 76mm or 2.9" and the holes should be clearanced at say .28")

    the way i came up with six bolts is: the spokes only accepted 3 bolts easily, so put those in a equalateral triangle in the existing holes in the sprocket. then i used the metal backing plate to line up an opposing triangle (think star of david)

    stacked everything up- aligned with three bolts- drilled the stack and mounted with (6) grade 8 hardened 1/4" bolts

    this went on flat, centered easily, and has just the right clearance
