sram apex front derailleur shims

For the life of me, I could not make sense of the shims sent with my apex FD! I love everything about the component group, but this shim system.

I am riding a 2009 salsa casseroll. There were no instructions or anything with it. There were plastic parts, metal parts, tons of different sizes. I put a little electrical tape on the frame to protect the paint from the metal spacer, and it slipped down the seat tube so that the cage is on .

Can anybody help me make sense of this?

I'm assuming the shims are to clamp to the seat tube. Are there any markings in mm on the shims? Use a caliper to measure your seat tube diameter and install the appropriate shims if they are available. If they are not, you may need to procure different shims or have some made.

edit: Common diameter on a steel frame is 28.6mm, so if your caliper gives you something within .2mm of that it is safe to assume that your seat tube diameter is 28.6
