Jessica installs a new radio in the '53 Packard, while Ron gets to the source of a weird sound coming from the new engine in a '68 Charger. Talon fits a custom-made driveshaft into the '67 Firebird before dropping the frame into a much cooler stance. Ron shows new hire Tommy the ropes tuning up the Packard, but it's Greg who gets to take her out for a cruise.
