After mount the caliper I seen it was hitting the carrier mount bracket to. I just took the grinder and shaved just a little off the caliper where it was hitting. You may not have to do this depending on how far you need to space it. After it was all bolted down, the disc was not dead center so I will be adding another washer and may not need the ground down spot on the caliper. If not, no big deal. I was ver little that was removed and will not hurt the strength of the mount at all. I have to run to the hardware store for more washers.
