Here's a nifty trick worth storing away in your noggin. If you narrow a replacement trunk pan before installation, you can position the lip directly over the framerail. Consequently, the seam is undetectable when looking underneath a car on a lift, lending the appearance of original factory metal. Likewise, cutting the trunk pan to the exact size needed, then butt-welding it in place, eliminates any metal that would normally hang down from the seam. "I want my replacement panels to look like factory originals. A lot of people these days have lifts in their home garage, so they're looking at the bottom of their cars as often as the top," Austin explains.
