Copper fittings in engine rebuild kit?

What is your question?

Hello! I have completed engine rebuilds before and I know that this kit is meant to be able to go with more than one engine, however I cannot help but wonder I am about to miss something. I have these, variety in size, copper o-rings that I cannot find where they belong too. The only thing I can think of is the alternator, where the positive power is screwed on or somewhere on the A/C condenser?
