The Gas Monkey crew is busier than ever as Richard Rawlings and Aaron Kaufman continue to take on one of their most demanding projects yet: rebuilding a '71 Dodge Scat Pack Challenger using parts from the 2015 model. This grand scheme turns into a mechanical challenge that Aaron and his team have never seen. Meanwhile, Richard invests in a new live venue space across from the Grill and is nervous he's going to have to spend every last dollar he has to do it. The mechanics also bring back to life a '57 Shorty School bus with hilarious results.
