In the process right now of sourcing the aluminum channel to replace the "L" brackets. I'll also have to rebuild the motor bases so they span the entire width new "U" channel brackets. The heads of the allen bolts holding the motors to the ply/aluminum base actually ensure the motors don't torque left to right by hanging down in the gap between the raised "L" brackets and the floor of the tank. They act as guides as the bolt through the center of the mount is tightened to get the optimum chain tension. Each motor mount is adjusted individually. I originally tried a one piece mount with both motors attached, but my skills as a carpenter failed me. My drive shafts are not in EXACTLY equal in all respects. After adjustment, the chains didn't have the same tension on both sides. The secondary screws to the left and right of the tensioning screw on the rearmost "L" bracket will be eliminated in the rebuild. They won't be needed. I only have them at the moment to reduce motor movement.
