PLZ HELP!!! 1972 gmc 6 lug 4 nub steel wheel backspacing?

Does anyone know what the backspacing is on the 15x6 4 nub wheels? i Have two four nubs and one measures 3.5 and the other measures 3 and 7/8. someone was telling me that the fronts were different from the rears. Is this true?

3.5 I would say. And they would need to be the same backspace or you couldn't rotate Them without switching the tires off the rim.
