Looking for Plim wedges - Joint 5x5

[Skaart]

Hello
Hope i get this post right, it's my first one.

I'm taking over some equipment, among other things a underpinner, Joint 5x5. It uses wedges from a Italian manufacturer called Plim, and I'm having a hard time finding these. Has anyone experienced this machine? Can i use other brands? Where can i get these wedges? I am located in Norway.
