The way you have explained it, you have everything in place except for that last O-ring. There should be an O-ring at the base of the splines that go into the end of the crankshaft. Did you have an O-ring just below the splines when you disassembled the unit? That O-ring (#76) is to help retain the spline grease between the drive-shaft and the crankshaft to keep them from seizing together.

The seal you have on the top of the hsg is correct. The o-ring you're talking about should fit in a gruve in the top of the driveshaft. Don't forget to grease the sides of the splines on the d/s and not the top.
