Below is a picture of the factory brake pad for reference. Note that the sensor mount is the standard type of mount that is found on many brake pads. However, note that it is offset by 1/2 - 3/4 inches to the right. I don't have a picture of the EBC brake pad because it's installed on the QP; however, it's the same mount, but situated in the center of the top edge.
It's possible that the EBC Red Pads that you have are of the older style? I've never seen an older style pad; however, there was an insert in the box that discussed a new anti-squeal backing that is now being implemented, which leads me to believe that there is an older style pad. I've only driven about 30 miles on the pads and so far no squealing. I hope it stays that way.
On an unrelated matter, I evacuated and renewed the power steering fluid using my air compressor and a vacuum container. That vacuum container was one of the best purchases ever - easy oil changes, brake bleading, and now power steering evacuation. Renewing the steering fluid was relatively easy; finding Dexron IID took me over an hour and visits to 4 different stores.
