Thanks. I want to confirm b/c I am trying to replace the seat and (I think) the OEM part number for the K1 is different from the K2?

K1:
77200-323-030A

K2:
77200-323-050A

Actually, I think I read the various parts catalogs incorrectly and both the K1 and K2 OEM seat assembly was 77200-323-050A whereas the K0 was 030A.

The '71 has a one year only pan, and seat latch (non-locking) assembly.

The '71 has a hook attached to the pan, and it has less space between the bolts.

You've got the '72-73 set up.  I'm not sure, but that pan may have been the same as the '74-76 550K's as well.
