Rear drum brakes
‘74 wouldn’t have 9” drums.
Uhhh...Yes, they could have.
In 2014 I bought 2 Dart Sports. The '74 had a slant 6 and 4 wheel 9" drums.
Going back further, in 2000 I had a '76 Dart 2 door, slant six 904 stripped down car. Heater and an AM radio seemed to be the only features. 4 wheel 9 inch drums again.
Even further back, in the mid 1990s, I was shooting a couple of movies in Northern CA using a Dodge Dart and a Plymouth Duster for stunt cars. I'd occasionally need control arms and other suspension parts. The Pick N Pull yards still had rows of A body cars then. I recall seeing drum brakes on several '73 and later cars. They were not the majority but they did exist.
A guy on Moparts claimed that there was a Federal law that all cars built in the US had to be equipped with front disc brakes as of January 1 1976. I can't confirm it but it may be true.
