It is the wrong caliper. Either way, the caliper needs to be flipped right side up so that the two empty bolt holes line up with the bracket. The caliper you are looking for has a bolt hole mid way down the body and one at the top. You can find a picture on Pandemoniums site.
good looking out and thanks but I'm aware - i think there was some confusion during the order...i apologize that my sarcasm didn't translate in my post
