There are lots of little things in this episode that the continuity master did not kep track of. For instance, the driver's side front wheel cover is missing in the opening shot of the green Monte Carlo. Next scene it is back but the rear is missing. In the first chase scene the front wheel cover comes off on a hard turn but it is back at the end of the chase when Jim cuts the valve. The warehouse that Rocky goes into in the beginning has a wood beam roof, but the rest of the time the warehouse has a steel beam roof. Sure these are trivial things, but it is a continuity master's job.
