Question on U13 and RWD Flywheel

[got2b240]

I have here a mint condition U13 Stock flywheel, clutch disk, and pressure plate.

I have measured the clutch disk and it came to 9 7/16'' just like the RWD clutch. Also it is 24 tooth, likewise.

Seems to me in comparison to some random pictures of RWD SR flwheels, that the threaded holes for the application of the pressure plate are same in number, and position. Also has 8 holes for the flywheel to bolt on to the crank like a RWD (all SR cranks are the same except for hole depth for flywheel mounting position).

Also seems that the teeth around the back of the flywheel are in the same respects to the pics of a RWD flywheel.

I was wondering if these are at all possibly the same, and/or interchangable? Has anyone ever heard of such thing? Or am I the first one who was wondering abou this?

Comments, facts, suggestions would be greatly appreciated

anyone know if the RWD and this flywheel are the same?

Well, I've been told that the FWD SR's (even JDM, I know the USDM SR has a much smaller diameter) have a different flywheel and clutch, but if it's the same size, thooth count, pressure plate pattern, and crank pattern, then I don't see why you can't use it.
