A customer brings in a 1972 Honda ATC. The front tire is missing, so Tyler has to search for one online. Meanwhile, another customer wants his grandfather's rifle restored. After Rick hires an expert to analyze the gun, it is determined to be a Revolutionary War musket, and that restoration would dramatically devaluate the gun. Also, Ron and Tyler plan a bachelor party for Rick. The party has to be "PG", so Ron and Tyler rent ATVs for them all to ride. Meanwhile, another customer wants an Edison phonograph restored. The phonograph had been his grandfather's.
