What is a 9421790370 Sleeve? (Edit: they are the retaining ring for the rear axles to hold in the Main bearing.)
I'm having a bit of a clean up/out and found four (Edit: 5) of these deep in a box from PA's collection.
Don't want to loose/ chuck if its made of unobtainium.
(Edit: Yes they are for sale, at the right price)
Edit: 2x sold pending. 3x still available 19/02/2019.
