I had to cut back the fins to clear the 10 mm bolt heads I still need
one of Tracy's spline plates to get accurate
dimensions off of it. Does anybody have one they can loan me?
Also is anybody interested in testing this right now. You have got to
have an engine and gear box running.
If so I will find the Ford TX part Tracy made his spline plate from
and buy one for testing.

Paul,
If nobody has a running engine on a test stand, I could test it on
my 3-rotor... ground runs only.
And YES, I want one.

Great Mark. Best man for the job. You have the most power and torque
of anybody.
I did not find a spline plate but most of the big auto tranny shops
in Ventura are closed today. I can order one from Slauson in LA on
Monday. Jean Proudhome sent me a picture of the part Tracy cuts the
spline plate out of. We will use that. No need to send yours Craig.
I'll will check the dwgs carefully again and see if I can find some
metric 10 MM flat head hex socket high strength bolts. That would do
away with the notch in the fins.

Hi Paul; I thought I sent an email for something similar to this
years ago. Those parts appear to be Ford C6/E4OD/4R100 forward drums
- there are many variants. Lots on ebay The spline is not full
depth on some later 4R100? versions.
IIRC, these are powdered metal parts. At least 1 person talked
about replacing the soft AL rivets in Tracy's splined adapter plate
with bolts - I'm curious to know if and how it held up? The excess
forward drum cylinder portions can be removed, to create the splined
plate, in a few minutes with a hacksaw blade with the drum mounted in
a lathe, and then finished. There are also stronger aftermarket 4140
billet versions.
Since you are already planning to CNC custom parts, have you
considered integrating the damper directly with the counterweight,
replacing or modifying the CW to save more weight? smaller
flexplates/ring gears, button race clutches?
Cheers Cary
To hog the counter weight and rubber coupling out of billet steel
would cost three or four times as much. Maybe ten times as much :)

Craig,
I had to replace the rivets on my 3-rotor damper assy. as they had loosened
and were beginning to "smoke". I replaced them with close tolerance 1/4-28
bolts. So far, they are working out fine. This should not be an issue for
the new adapter, provided the bolts clear the blades of the damper.
