AZ8 thrust bearing sizes... Repurpose as Equatorial for imaging?


 
Edited

Hi all, from the imperially challenged other side of the world (South Africa).
?
I have an AZ8 acquired from local astronomer enthusiast Douglas Bullis with a beloved Intes Wirth (APM Markus Ludes) MN86 purchase.?
?
I am missing the RA clutch needle thrust bearing, which I assume is the same as the GM8 and trying to source one locally before importing it from the USA. Can anyone suggest proper sizing on this bearing? Presumably, thickness will not be a concern. The Losmandy website states one 2.100" diameter needle thrust bearing, one 2.000" diameter needle thrust bearing.
?
I am hoping to convert the AZ8 to equatorial by making a wedge where the bottom flange can bolt onto. This seems like a simple, non-destructive modification unless I'm missing something. Will also need to fashion some kind of counterweight system... Unless someone would like to trade for something equatorial with 30lb payload capacity?
?
I do not see a serial number. I have the flat machined section for encoders and a polarscope hole with brass gears and worms.

Any advice here would be greatly appreciated. I tried to join the Losmandy hackers group, but it seems they are not taking any more members.
