Keith I would refrain from doing anything that would restrict full engagement of the dogs, I personally would not worry about the mismatch of the gears, however as you have a built up layshaft you can either grind the spindle or the gear to improve alignment. I have recently refurbished a vintage gearbox that required all new bushes, and as the sleeve gear was badly worn and pitted I took the opportunaty to grind the diameter and backface of the gear this required an undersize bush with a thicker shoulder to take up all the end float, the only problem with this is the need to mill part of the new bush away when fitted in order to clear the layshaft gear when you have a vintage solid layshaft. Good luck. Alan Noakes.
