original 1972 squad was moved to the third truck. The only discernible with this truck were the black vinyl trim covers on the insides of the cab doors. The two previous truck cabs had all metal doors with no vinyl covers. Interestingly, when filming of "Emergency" began in 1972, the L.A. County Fire Department began to switch over to Ford trucks. In the series, some stock footage shots showed the squad as a prior generation 1970 Dodge D300 model. As the show progressed, this footage was no longer used. The original gasoline powered 440 ci motor is still in the vehicle. The restoration cost was about $30,000 due to the restoration being a complete "frame off" restoration. In the TV movie Survival on Charter 220 where Squad 51 was crushed, a previous generation 1970 Dodge D300 was used to take its place. Squad 51 contained actual medical equipment including a Biophone per the Los Angeles County Fire Department specs of the era. See also Biophone Engine 51 Emergency!
