CPP Disc brake caliper question..

[IHutch5R]

I've got my disc brake conversion all on the truck but in the box the calipers were in were these washers and I can't figure out where the darn things are supposed to go. There are two for each side and there are two mounting bolts that they fit on, i just cant figure out where they are supposed to sit. If anyone has done this kit before and can tell me or just knows, it would be much appreciated. I want to drive this thing already.
