Yes, the locating pin hole that ensures the dually wheels are lined up properly, not the bolt holes. The locating pin hole on the Ford wheel sits closer to the hub hole than the Dodge wheel. The simple fix is to cut the locating pin. Replacement drums don’t even have the pin anymore.
That's what I thought. Your motorhome has the pins??
The alignment/locator pins are left over from the 30's, 40's, 50's, and maybe early 60's. I've never seen them on anything newer except for my 1972 M375 with 19.5 Budd wheel rims. (You'll see the pins on military vehicles, for reasons know only to the military.)
I grind the pins off whenever I encounter them. (Yes, I sometimes work on really old vehicles and trailers.) And, true, drums and rotors no longer have the pins. If you find one with pins, it's probably NOS ... or NROS, as in New, Really Old Stock.
Coined bolt holes align dual rims properly, so no need for the pins. (Most old-timers I know don't even know the original reason for the pins.)
Rims still have the alignment/locator holes/slots so people can use them on really old vehicles. Or, "that's the way we've always made them and I don't know why.")
