Question for David, Kelly or anyone else playing with lightweight flywheels.   I have one on the way but won't see it until I get back home in October.   I'm working on a new design to replace the stock flex plate and need to know the thickness of the lightweight flywheel.  Every picture I see of them appears to show an almost flat disk which would imply that there is MORE room between it and the redrive  adapter plate than there is for the flex plate which has about a 1 1/4" dish in it.   BUT,  much of the discussion seems to imply that if anything, there is LESS.  

Anyone able to tell me the actual thickness of these aftermarket lightweight flywheels?

I'm looking at the aluminum versions for weight reasons and also because the iron friction surface is removable ( for even less weight).
