I recently installed a new version 5 chassis on my grandson's "Big Hauler". The Big Hauler weight did not quite fit. I cut off one end of the weight to open up the slot. Then with a washer on the original screw I was able to secure the weight. It was a ten minute job. ![Smiley :)](https://www.bachmanntrains.com/home-usa/board/Smileys/default/smiley.gif)
