76 breaks problem

Rockauto shows Centric 123.63020 for your car (1976 Dart, front disks). Their Centric listings are best since give all dimensions and photos.

Strange if your rear wheel bolt circles was 5x4"D. Does your spare wheel fit both front and rear? You can find many photos how to measure bolt circle. Show how you are doing it. Strange that you measure the OD of the drum, not the ID. Report back, don't leave readers hanging.
