Tracy,

Mine is different from the aluminum o= ne that you are looking at, but I wold be pretty sure that they all put the= friction surface in the same spot... which would be the same spot  as= the stock flywheel - if you have one of those.  It is, indeed, slight= ly closer to the gear-box than the current set-up.  Mine is not a flat= disk, and I wouldn't think that the aluminum are either.  I posted a = bunch of measurements early in the discussion and they were all pretty clos= e (though I did end up taking a little too much off my starter to get it to= reach). 

I machined down my friction surface, but still had t= o take a few thou. off the spline to get it to fit.

Sorry I cant dig= up the numbers right now, in a hurry getting ready to leave for Reno in th= e Morning.  I have about 10 hours on the new flywheel.  So far so= good.

Also, If you follow Paul's site, he is coming up with a very nice solution that may not be too expensive, heavy, or difficult and = incorporates a really nice improvement in the rubber dampers too.

I'm looking at the aluminum versions for weight reasons= and also because the iron friction surface is removable ( for even less weight).
