I would like to hear your take on this.

Both Minot AFB and Tinker AFB had runway numbers change a few years ago.

Interesting, but the directional designations are still L & R. For those airports that use N, E, S & W...I would think those will still remain the same.

But your original post stated "renumber" which I imagine would depend on the number of runways available. Not direction.
