there you go sorry it took me a while. As you can see from the picture, the 944 caliper bolts right up onto the caliper mount.
so from what people have said, the 996 and boxter caliper mount the same but the face is rotated 90 degrees. I think this is right sorrect me if i am wrong
Will try and do some reasearch as soon as i have a minute, got a few more leads to go on, but i think it is definatly possible to do.
