Once again I spent some time tweaking the Canopy and finally drilled the 7 holes for the side rails. The rear one gets a 1/8 X 7/16 X 1/2" spacer under the canopy deck. I also added a nice touch by buffing up the Lt rail on the buffing wheel. I have supplies from my acrylic manufacturing days so it wasn't a problem to clean these right up. Right tools for the right job.
