As a cautionary note...
I know you're working on a RHD, so this may not apply.
I've got 4 LHD boxes at present. If memory serves, 3 of them have a 2 groove/3 ridge sector gear, and the other has a 1 groove, 2 ridge sector. There are at least two different worm gear shaft ODs. None of the worm gears will match up with a sector from a different set.
However, measuring by eyeball, it looks like matched gear sets might replace another set, so long as the input (worm) shaft sizes match.
I looked at the referenced supplier web page, and see they offer some sector gears as well. If you find the worm you ordered fits your shaft and box dimensions, but isn't a happy mate to the sector, perhaps another Ford piece will bring it good. When I get home I'm going to look into this, partly In hopes the bearings they offer will fit as well.
