Hi Dave,

Do you remember what that flywheel weighs? Was i= t the same diameter as the flex plate, or was it smaller, like the non-turb= o manual trans flywheels? Did you remove all the disk mating surface to red= uce weight, or just enough to mount the damper plate?

I've got a= n aluminum manual trans flywheel on the shelf, but it's slightly smalle= r in dia than the flexplate. Wondering about weight comparisons, mounting, = etc.

In more general terms, the flexplates seem to have a rather che= ckered past even in the car. I've got one that came off the car cracked= .
