AZ-EQ5 tuning and replacement parts

Hey there

I've been tuning my AZ-EQ5 to remove some wiggle/play as per these excellent instructions that someone posted on CN:

What I've found adusting the D and E screws is that there there is a point where the R.A pinion is unevenly spinning, where it's loose 80% of the rotation and tight the remaining 20% and I am unable to remove any more play without causing the pinion to be too tight during that 20%. It seems the pinion may not be perfectly straight as clearly it's engaged too closely for part of its rotation.

The Dec. axis is even weirder, it rotate perfectly 95% of the way, the remaining 5% is basically stuck, as if the thread on the pinion has a notch in it.

I'm wondering if anyone knows where to source replacement gear boxes, or even just replacement pinions (although I imagine that to be very fiddly to replace, pulling apart the gear box and all).
