Rear 5100 install bushing question

[hawee99]

I'm a little confused on the order of the bushings for these rear 5100s.
My hardware kit has two different styles of bushings. And from what I can tell from a few installation videos I found, the two bushings should be the same. both with a slight edge on them, like the screen shot attached.
Is anyone familiar with the order of installation for the kit I have?

Nevermind. I just looked at it again with a fresh set of eyes and I think it makes sense.
I don't see any way to delete a post on here. But I will take a picture of the order once I get around to it in case anybody else has the question later on
