‘75 Dart Sport /6 which rear bearing size?

I wanted to take a brief moment to thank everyone who chimed in on my Dart’s rear end! With all of your help I was able to order the correct bearing parts & seals; for the rear end (that I was previously unable to identify).

I took a few pics but, was learning along the way (and didn’t take any while we pressed the new bearings back onto the axles). Also, for what it’s worth... removing the seals was a bear to get the OEM ones out.
