Thanks I see 2 internal tooth washers and 2 nuts called out, so they'd simply have to install between the bezel and chrome knobs then.
Just to clarify, my question was only to do with what goes over the left and right shafts - how many and in what order.
I had envisioned more than one washer and nut per shaft is all, and I couldn't make out that fuzzy, small diagram pic.
