How to properly measure axle width

[Cj7355]

Was wondering if anyone could tell me how to properly measure my axles in my 1980 CJ7 , they’re stock Dana 30 /AMC20 need to figure out if i have narrow or wide tracks. It’s a used jeep so who knows if they were swapped. I’m assuming you measure from the face of the axle shaft where the wheel mounts to the other face of the other shaft? Also does anyone have the stock widths of narrow/wide tracks. Thanks in advance.

That’s narrow and wide track widths for the AMC20 correct?

Those measurements are the WMS-WMS (wheel mounting surface).
