Bus Heater Flapper Valves – Style 2
Heater Flapper Valves for a Type 4 Bus. There are two styles of heater box flapper valves for Type 4 Buses – this style pictured and this style without an extra curved tube. Both styles with fit 1972-1979 Buses, but we are unsure which styles were originally correct for which years and/or options. We most often see this style in the later Buses, however.
