Bryan=20 and Jeff,

 Jeff,

The grooves for the outer = water jackets=20 are in the rotor housings vice the side=20 housings.

The rotors have an additional = outer=20 ring.  Some of the tolerances are not in the DVD due to the = fact that=20 these components are unique to the = Renesis.

I can get those to you if you = decide on=20 the Renesis.  Otherwise, pretty much the=20 same.
