Hi,
They are available thru special bearing stores, at least in europe.
I have bought some for my own throttle body design.
They cost about 2,00$ each.

Hi Arne-
I haven't heard from you in a while.
It sounds like you have been making great progress with your brand-new throttle body design.
Best of Luck !!
Merry Christmas to you and yours...
Ronnie
