I`ll try to make some photographs for you,but in my head there is the information,that these rings are only made of a soft steel,noway that they are herdened(original),and theres no chrome on them....
But :`til weekend i´ll see if i find them w/o 2days to look for.
Otherwise it should be possible that other manufacturers have found other specifications,but the prices...
Let me see...

I try buy the bearings kit from Summitracing, now I wait for answer about bearing wide.
