On the left is an input bearing for a Muncie. Cook says this bearing costs approximately $80 to replace. On the right is the same bearing for a T10. It is approximately 1/3 the price but is too wide and won't fit a Muncie. Cook, however, fabricates his own spacers to make the T10 bearing work in a Muncie. In addition to being significantly cheaper, the bearing also features rubber shielding that protects the bearing from grit while also preventing leaks.
