Anet A8 Basic Y Axis Upgrade

SInce I upgraded the X axis in a previous project, I figured that the Y axis should be looked at. The Y axis has the same undersized rods and terrible bearings. I upgraded the bearings with the same bearings I used in the last project, (Ina Model KH0824PP) by just disassembling and re-using the existing metal pillow blocks.
