Replacing Alt and Az knobs on an EQ6R Pro

[StuartT]

Like others, I am frustrated with the Alt and Az adjustment bolts on my EQ6R Pro. The knobs on the Az bolts are not great and the loose ratchets type knob for upward adjustment is awkward to get fine adjustment with.

I think the knobs on both can be replaced for more suitable ones. Does anyone have any suggestions for this? If so, what are the bolt measurements? I think the az bolts may be M10, but I think the Alt one is bigger. 

Advice would be welcome!

Thanks

In case anyone needs this info, I've just heard back from SkyWatcher in China about the sizes of the bolts

Az bolts - M12 (coarse pitch, 1.75) 89mm
'top' Alt bolt - M12 (coarse pitch, 1.75) 78mm
'bottom' Alt bolt- M16 (coarse pitch, 1.75) 97mm

All bolts need to be bullet nosed (i.e. with a domed end)
