SP1 piston ring install - F500 and Snowmobile engines

Now you're scaring me lol. My piston rings seem to both be the same size. I also have the spi brand. How do you tell which ring goes in the top groove and wich goes in the bottom? Awesome video!

They were drastically different thickness. It was noticeable just in my bare hands but if you get your calipers out - you should be able to measure them and the thinner one goes in the top right, and the thicker one in the lower.
