"Here's the thing" about roundback/ squareback.......
Yes roundback ISOLATED (sometimes called "dual field") were made up until squareback, BUT THE THING IS
cheap *** rebuilders have "converted" a lot of older GROUNDED field into the 70/ later ISOLATED FIELD and done so INCORRECTLY.
WORSE, some of these "converted" units "somehow" get GROUNDED BRUSHES installed, AS WELL AS up through "squarebacks" ALSO COMING THROUGH with grounded brushes or broken or missing brush hardware which INCORRECTLY causes one brush to be grounded.
ALWAYS CHECK that your "isolated field" REALLY IS isolated!!!! Neither brush should be grounded!!!
Below, on left is one I did not know was made until recently, is it Mopar or aftermarket? If you look closely it has a GROUNDED BRUSH installed, yet it has a spot to mount 2 ISOLATED brushes:
(On the right is a "regular" squareback)

Below is one of the "junk mexican" rebuilds this is a 69/ EARLIER grounded brush unit that has been "half ***" converted to isolated field:
At 6 O'clock is the position for the old grounded brush. The "half ***" brush is at 12 O'clock, they just drilled a hole and popped a screw into the case
Below is ANOTHER one "you have to watch out for." This APPEARS to be a "normal" squareback WHICH SHOULD BE "isolated field" BUT IT HAS ONE BRUSH GROUNDED
