Somewhat rare?
I would say somewhat, yes. They're for three speed manual, correct? They mention
two levers, which would be three-on-the-tree 3spd, and not auto trans 3spd (with one lever).
I bought a set of them on Ebay back when I rebuilt my 3-on-the-tree steering column. You can see below where it sandwiches between the two levers in my before and after pics.
