I came across a set of ABS panels on eBay and emailed the seller to see if he could make a full Westy set. Turns out they look pretty damn cool installed! Cutting holes for the speakers was a trick. I had to build a custom circle jig, and the mounting positions are different in each door, so it was a lot of measuring and remeasuring with my digital caliper.
