Is there a significant difference in the measurements
of these two flywheels? Can they be considered to be the same for our
purposes?

(2) From
cter-wt to pressure plate/ring gear
surface 1.100
in (27.940 mm)
(3)
Flywheel thickness minus clutch disk
surface 1.100
in (27.940 mm)
"ACT"

thickness ?
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).
