Bulent,
What did you do to make it compatible, then? I would be interested in
seeing pictures....Tracy did tell me the 3rd gen flywheel does not fit
his redrive, either. Did you modify the one you had?

Hi Marc,
The 20B/Cosmo flywheels have few differences:

1 The ring gear is wider (teeth are longer )

2 The teeth are beveled on the back side since the starter engages from the
back

3  The holes do not match Tracy's pulse dampener.

I wanted to keep the starter and the bellhousing. So I made a disk from 1/8"
cromaloy to fit just inside the ring gear and matching holes for the
existing ones on the fw. Than match drilled holes to fit Tracy's pulse
dampener. Nothing special. All the dimensions are in front of you. All you
have to do is cut the disc and match drill 9 holes. I have no pictures since
I never thought I'll need them.

Gee, that sounds too easy. The flywheel you describe sounds idential to the 20B and to the 13Brewtt auto tranny types. Thanks for the information.
