Hey guys - I need to replace mine too on my 91RS.

In the FSM it shows just above the seal another non-reusable part called a U-PACKING

Any idea what this is and where to get it? I dont see it listed amongst the other parts at places like RockAuto.

Or should I not mess with it? Just remove/replace the bottom seal and that's it?
