Nice job cleaning things up. Might be a good time to reinforce the skin/flooring under the drop section where your feet go. Put a thicker skin there. As the tracks stretch and you move the front axial to tension the tracks, at a certain point ice or other debris caught in the grousers will start rubbing on the angled floor section as it goes around and can even wear through the skin. There is a reason Thiokol got rid of the angled floor design. Just a thought -
