Fuchs hubcaps,center caps
 

Please help me with this:

I recently bought a game of used 8",8.5" fuchs wheels ( 8.5 repro ). But I don´t have the centercaps.
I have 2 games of cookie cutters wheels but the hubcaps don´t fit my fuchs wheels. The hubcaps are wider than the hole of the fuchs wheels.

What kind of centercaps I need ?, because I saw in some catalogs that the fuchs and cookie use the same hubcap.

Thanks and regards
