The first Cush center had the usual deep splines.
Ya can use a late issue with the early engine but can't use the early issue center with the late engine. ............lm

Notice the larger blocks of friction material on these discs. The new 020 discs are the same dimension from the inside diamter to the outside, but they are smaller side to side so there are more blocks per disc in the new 020's than the old ones.
The clutch center has a raised area at the center bore that fits into the Cush pressure plate and the pressure plate has four holes in between the spring retention bolts for improved oil flow.
The clutch basket has "fingers" with arch shaped castings into their outer surface. It also has at its bore grooved oil passages in a spiral fashion that non-Cush baskets do not have. Also for improved oil flow, I've been told. The Cush basket is attached to the sprocket by rivets with neoprene washers "cush-ioning" the forces of clutch engagement. You can't see those, but you should test any clutch basket before using it by trying to spin the sprocket independent of the basket. If there is play that you can feel, time to pitch it in the trash.
Lastly, the Cush setup uses a nearly 3mm "A" plate as the steel plate closest to the sprocket. I've taken apart a few clutches lately and only one of them has had a true "A" plate that is nearly double the thickness of the other steel plates (1.65mm) in the clutch setup. Honda still sells what it calls an "A" plate but it measured only 2.1mm.
