They are identified by a small spot drill on the side. 1 is the tallest and 6 is the thinnest. They allow you to run new tires and go all the way to the rim with no stacking of shims. I liked the idea of not stacking because of accumulated error that can occur with the tolerance of shims. These shims are identicle within .0002 and are dead flat. Let me know what you think

By the way, I took into account the countersink on the chassis mounting surface that we all discussed and incorperated it into the shims.
