Tracy,
Mine is different from the aluminum one 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, slightly 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 close (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 to 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 the 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.

Question for David, Kelly or anyone else playing with lightweight flywheels. I have one on the way but won't see it until I get back home in October. I'm working on a new design to replace the stock flex plate and need to know the thickness of the lightweight flywheel. Every picture I see of them appears to show an almost flat disk which would imply that there is MORE room between it and the redrive adapter plate than there is for the flex plate which has about a 1 1/4" dish in it. BUT, much of the discussion seems to imply that if anything, there is LESS.
Anyone able to tell me the actual thickness of these aftermarket lightweight flywheels?
I'm looking at the aluminum versions for weight reasons and also because the iron friction surface is removable ( for even less weight).
