Hello Charlie,

=C2=A0

No= I don=E2=80=99t remember what the flywheel weighed, but weighing parts, my= installation weighed 3 lbs. more than the original assembly. My aluminum f= lywheel is smaller than the flexplate, so I had to move the starter. I took= nothing from the disk surface except to remove the steel face. My smaller = resized spline hub was made to fit where the steel clutch face was original= ly.

Hi Dave,
Do you remember what that flywheel weighs? Was it the same diameter as th= e flex plate, or was it smaller, like the non-turbo manual trans flywheels?= Did you remove all the disk mating surface to reduce weight, or just enoug= h to mount the damper plate?

I've got an aluminum manual trans f= lywheel on the shelf, but it's slightly smaller in dia than the flexpla= te. Wondering about weight comparisons, mounting, etc.

In more gener= al terms, the flexplates seem to have a rather checkered past even in the c= ar. I've got one that came off the car cracked.
