Was wondering if someone could give me some information? I am setting up a Flathead with a Chevy trans.(Muncie) am planning on using the Offenhauser adapter, with a Chevy throwout bearing and arm, with a Ford 3- finger pressure plate and Chevy disc. Does this work good or do I need to go to the Chevy pressure plate and re-drill the flywheel? Any help would be appreciated.
The only possible point of incompatibility would be where the throwout bearing meets the clutch fingers. As long as the input shaft length is correct after installing the adapter and the spline matches the disc, the pressure plate doesn't know the difference. Check to make sure you have good contact between the bearing and thefingers and that the bearing isn't too thick (or thin) to provide adequate travel. quote=tg33chevy;2387014]Was wondering if someone could give me some information?

When we do this conversion we use a Ford PU 10 inch Diaphram PP with a pattern that matchs the flathead flywheel. The PP works well with the Chevy throwout brg. The Long 3 finger PP is not compatable with the smaller Chevy brg. See your local clutch place for the correct part.
Do you have any more specific application data for this pressure plate other than Ford pickup? Engine, year, etc??
I checked with Napa and they have one for a `53 Ford P.U. 239 V-8. It`s 10" diaphram. (Boy my spelling sucks.)
You can call Flathead Jacks in CA. I believe he has the adaptors (chevy) , and can answer your questions. I bought a Weber clutch for my father 10 yrs ago( flathead), and I just installed a Weber clutch /aluminun flywheel for a flathead in my coupe. Very satisfied with the parts ,and service.
