Appropriately 2 1/16” - 2 1/8” opening on Ford pack nut wrench.

An 18" Bahco [crescent] adjustable wrench works fine for me.

If you have a reproduction pack nut, the factory wrench may not fit. I've run across several of the reproductions that were at least a 1/16" oversize, the ones that are more simply machined without bevelled corners tend to be the worst.

The big shifter fits all variations.
