23mm 40series offset wheels?

[Dafni]

Hm, thanks. It's a TwinForce. I think the ones you found require this set-screw in the axle... Savage stuff would work. Or I could buy these, make a groove in them on a lathe and put an O-Ring over the pins. Would be just a band-aid though, and I need someting proper. It's a customers truck.

Got another suggestion?

Thank you so far! Appreciated!
