I have some plastic piece between motor and chassis reinforcement, which keep the motor to move latteraly, and it give me information on the shimming too.
And I can feel it with the play between pinion and spur when I move the spur up and down.

zeen... I get a little confused myself when meshing metal gears... with plastic spurs and metal pinions i used the 'Paper Method'... running a sheet of paper
between the gears to achieve a relatively good mesh... But I'm sure if that method can be used with metal gears...
Some people do that with metal ;)
But I prefer the hearing method, I hear carefully the noise that my mesh is doing to adjust precisely the shimming. I use my eyes too, with habit you can see a proper or bad mesh, and the noise confirm it !
