My English axle has a 4.11 diff and I am going to replace it with a 3.54.This diff has the pinion in place and correctly loaded.Does anyone know the correct adjustment for the crown wheel to pinion meshing via the holed rings.What sort of backlash on the prop flange should i look to achieve

There's an article in this months ClassicFord telling you how to set it up.
