AA 20" Wire Wheel Question

[Bruce in southern OH]

Need to find out for a friend if the early 20" AA Wire wheels will fit on a late 28 large drum. ( bolt pattern is the same ) I know that some early AA trucks had car drums and they changed to large drum with "dish" rims. We want to install the wire wheels on the "dish" large drums. Thanks Bruce
( he lives 1100 Miles west of me, I have wire wheels here )
