Hi everyone! I bought a partial set of Ford piston rings and they don't have any information on which is which! I know the bottom oil rings, but the 2 top rings have me second guessing myself! The one that is wider and greyer has a dot on top, but a bevel inside facing down (I'm guessing 2nd ring?) Then the other one is black (possibly nitride coated?) And I think it has a moly outer layer, but no dot or markings or bevel! I'm guessing it's the top and that it doesn't matter which way it goes in. With the oil ring, where the ends meet, do you put them tips up or down? I've seen both ways. My set is- f7tz 6148 aa
