Technical 9 inch axle seals

Which number is for the correct seal.

 

this is what the book says

 

I keep a note book on every car I build or work on with the part numbers and where I got them along with cost, makes replacing parts a lot easier.

 

I've been meaning to make that notebook for a few decades, now....and with my memory getting feeble, I really ought to.

 

The next time I go to a store I am going to get a few notebooks to keep part numbers in.
