Thanks rabbit that's what I thought, perhaps the 11-12 lbs is too optimistic. I spent about an hour with the shop and we agreed the target weight may be a little optimistic. We(he) are shaving down the part in between where the pressure plate will bolt as well as leveling the back side flush to the ring of teeth (about .100 of an inch). What is important is the location of removal n it is being done there.
