Can someone who's done this mod dumb it down for me.

First off the spacer Nick mentioned needs to go between the two brackets is it really 0.4"... that's 10mm. That seems big to me. If that is right am I suppose to just use a bunch of washers?

Next could someone explain how the brackets go on. I go the pins at the top, bleeder at the top part.

1) So does the Boer's bracket adapter bolt to the back side or the rotor side?
2) Once that's in place does the caliper bracket go on the back side of it or the rotor side of it?

FYI you will need to buy 8 M12 bolts to bolt the brackets up.

Any help would be appreciated. I am also taking some pics to help anyone else through the process. Quick responses would be great as I need this installed asap.
