Bendix lists the same 11" drum from 66-89.
Dynamic Friction lists the same 11" drum from 65-89
Centric lists the same 11" drum from 65-89
NAPA lists the same 11" drum from 65-83
Interesting. When I look up Napa, they list Part #: ND 4401168, 11" X 2 1/2" Brakes, Dodge Charger 1970-1978, Coronet 1970-1976.
The Raybestos website says 2953R, 11x2-1/2" rear drum, 1970 on.
Now Rock Auto does something weird, but I find errors on their site all the time. Bendix PDR0365, 11" rear drum, shows Coronet 1970-1976, but Charger 1967-1978, Raybestos 2953R, 11x2-1/2" rear drum, Charger 1970-1978, Coronet 1970-1976, and Centric 12363016, 11" rear drum, Charger 1969-1978, Coronet 1966-1976.
