Well that's my 2 cents and I hope this helps and makes your job a bit easier.
I agree with this^^^^
The gears are manufactured to a particular dimension as far as spacing and center line are concerned.....but.....the housings are manufactured with certain
± tolerances as well...which may or may not be the exact same as what the gears are.
The last set I put in my 12 bolt...I set the depth to exactly what was marked on the pinion gear......it wasn't anywhere close when I checked the pattern...
