MiM F bass tuners fit W's standard tuner ream?

[Day-mun]

W calls it a 17.5mm ream,  Schaller says BML's require 11/16 ream, and BPR (supplying Genuine Fender replacements) says the Mexi/Highway 1's require a 11/16 (18mm) ream... so do they fit or not?

I'd be surprised if Schaller don't actually work in metric and, FWIW, 11/16" = 17.4625mm not 18mm

That is what I was thinking, but I wasn't sure if that fraction of a millimeter difference between websites came from one website rounding it of to the nearest metric figure, -or if there is truly a difference in size between the BML's (that W reams for and sells) and the MiM fender tuners. -They both (well, two outa three) called the ream 11/16", so that is where my suspicions came from...

-Reason I ask is I plan to hand a neck of mine off to someone else (-sans tuners), and I'm just curious if they are going to have any trouble cannibalizing the machines off their existing instrument.

Maybe here's a better way to ask: Has anyone ever put MiM Fender bass tuners on a W headstock reamed for Shaller BML's? -How'd that go?

...guess I can put the calipers on the Mexi's posts and see if they are the same as the Schaller's; perhaps the half of a mm comes from (possibly) chunkier MiM bushings with no difference on inside diameter(?)...
