I already did that. I have my disc reversed so the splined hub is facing the trans. I have always installed my clutches like that. It is the oposite way that is pictured in your diagram above. on the GM 3.1 it wont fit the other way so I thought all setups were like that.

Most friction plates come with an arrow or at least a sticker that says "this side toward motor." I always assumed that friction plates were intended to rotate a certain direction... are there any such markings on your clutch?

After thinking about this, I'm frankly not sure whether the direction is critical for a new clutch, as long as it physically fits (on some FWD cars, the flywheel is really dished out in its center)... as I visualize a friction plate, I can't see how the friction material, engagement dampers, or marcel plate would particularly care which way they are turned. Some clutch plates have the friction material aligned or slotted with a radial tilt, so I imagine they might be different, but a symmetrical clutch plate... hmmm...

Let me beat this dead horse a little more. <img src="/forums/images/graemlins/pfft.gif" alt="" />
This article is along the lines of what I was thinking -- customizing the hub;s position relative to the friction material:

Can you approximate the relative offset of the hub boss to which the friction material is riveted (offset + boss/flange + offset = total inner spline length -- what are the first three dimensions?)? If you've got the old clutch that came on the motor, you could drill out the rivets and measure, otherwise, you'll have to approximate. There's some interesting pics at: http://www.tegger.com/hondafaq/clutch/
Down at the bottom, you can see the offset, a bit. Cool pic of a naked marcel, too.
