2. After looking at the rear wheelwells, we noticed that with some work and a bit of cutting and folding we could easily trim 11⁄4-inches from the lip of the wheelwell. The bad news is some of it would require sheetmetal welding. Other parts are easier and only require relief cuts with the air saw and a good talking to with a ball peen hammer to get sharp pinch welds safely away from tires. To help us make clean cuts, we made this little tool to draw our cut lines on the body. We made it out of some scrap aluminum that we bent and drilled a hole to fit a permanent marker.
