Engine alignment

[jpblue1000]

Ok guys have swapped out a swb comp chassis with a 535mm lwb one. easy enough swap but whats the best way to square up the engine assembly to the diff assembly, to ensure the two gears are running true and square. Is it done by eye and feel or is there a more scientific way.
Cheers

Mostly done by eye, feel and experience.

You can run a piece of paper between the layshaft cog and the ring gear on the diff and see which way the both are tracking (see if there is even pattern on the paper).
