Paul,
Could you send me the table on rotor weights again.  I just saw mine the
other day but can't put my finger on it when I need it.  I *must* get more
organized.  Also do you know the eccentricity of the 13B?  I'm trying to
figure out the proper torsional stiffness of the clutch plate for my prop
drive.  I've already looked a few clutch plates at the local NAPA to
measure the springs and calculate the stiffness.  I have to drive south
about 1/2 hr. during working hrs. to measure an RX7 clutch plate without
buying one.  Do you have one?  Although the requirement depends a little on
the drive config, I'll share my results when I'm done.  Please send info to
my home acct: twotikes@aol.com so I can use it over the weekend.  Thanks.

I can't find that table. Can someone help out. Racing Beat or Mazdatrix
probably has that info. I do not have a Mazda clutch plate.

The eccentricity is 15 MM 
Rotor journal diameter  74 mm
Main journal diameter 43 mm
