This should help identify the seals in the box.
You will likely need new gaskets for the clutch and generator covers and the oil pan. Will need a threebond or similar product to seal the cases.
There is also a bit in the repair thread about sorting a tool to get the seals off and on.
They replaced quite a bit of other stuff and left question marks hanging over the missed opportunity to replace crank seals.
IMHO if it isn't broke don't fix it especially if it could be done later with the motor on the bike. When you start into stuff it can unravel.
An exception might be the oil pump o rings. It's a shot to nothing.
