Part match up problem - Orion Pobursky - 2019-03-07

Attached is a snippet of an official model I am working on. 

The steering arms (2739a) and the steering links (6540b) should match up with the arms at 90 degrees. I'm posting this to see if this is a problem with one of the parts or if I'm doing something wrong.

My bet is that 6540b is slighly off. (6540a is the same). Distance in z direction between towball and pinhole is 22 ldu, I guess it should be 20ldu.

I don't have this part but it's pretty cheap so I can order it.

I just ordered both versions so I can double check you.

I came to the same conclusion. Something is off by 2 ldu. It could be either the pin/axle hole or the towballs.

Clearly distance should be 20 x 70 ldu, not 22 x 70! https://photos.app.goo.gl/WEAjRxRjqAWTaJwRA
Position of towballs vs. ring are OK. I'll correct...

6540a and b now corrected on PT.
