I looked at the rears when I was cleaning up my tools and noticed that they where not the same as the six I have on my Coe (which are the two piece split in the middle as you described). I went to the front and they were the 7.5 x 20 split in the middle also. I looked at the rear again and could not see where they were split. I will bring them home Monday on the axle and get a closer look. I will post a pic. Maybe I lost my mind (the wife thinks I have).
