Yea that is MonsterMikes original slipperential setup, and I believe he only produced like three or four of them as a test platform which was followed up by the RCM universal center diff/motor mount kit and his patented diff style slipper system. So yes very rare, and probably worth a few pennys for sure. They are kind of neat looking, and very solid construction, but a bit overkill compared to what is available now.
