Piston ring question
 

Anyone able to help determine which grove and which rings go where? I have purchased a perfect circle by mahle ring set and received no instructions with this box. One set of compression rings has a "o" marked on the ring and no coating on the side of the ring (which I think would be the top ring 1 with the "0" pointed up. The other ring has a bevel on the inside diameter with no visual markings except a pin head mark and DOES have a coating on the outside edge of the ring. These 8 rings with the bevel, all have the pin point mark in the same location on one side. Is this going to be my 2nd ring from the top of the piston? and will the bevel point down or up? I may have to call mahle on tuesday if i cant figure this out.

The compression ring is the top ring, I can't remember how the bevel goes on the center ring. I can look in my shop tomorrow if no one else has answerd.
