Honda part numbers. "what are these?"

[alph]

a few years ago I ordered a bunch of gaskets, drive shaft, pinion cup, and other parts from HDL.  when I got my order I placed 'em on my shelf of spare parts and forgot about them for the summer.  (I like to have emergency parts just in case I have to go through that whole "universal joint shortage" thing again)

so now I've got these parts that I have NO idea what they're for, or why I even ordered them!!  either HDL made a mistake, or I got overly prepared for some horrible disaster!!

here are the parts, two are oil seals;

91262-MY3-003
91261-ME9-005

one is a metal "thing";

41433-MG9-000

I obviously was trying to "prepare" for something, or else I would have never bought them.  

I thought that by putting these parts into HDL's search window it'd direct me to a description, but it didn't..... any help would be great.

thanks.
