Problem with revolute mates

Hi
I need some input regarding revolute mates in the model I am working on.
It is a heavy transport module in scale 1:24, and I am trying to get the steering to work. The problem arises when I want to connect side A with side B. Steering from front to back (left to right in the drawing works fine).
When I try to insert revolute mates on the yellow markings all other revolute mates turn red, and everything locks up. I have tried to make the mates in various order (start with the yellow ones, end with the yellow ones), but the result is the same.
Any input regarding this would be very welcome.
BTW: Is there a way to measure angles in the assembly? I would like to know the angle of A, B etc., so I get them to be in the correct relationship.
And here is the link to my document: https://cad.onshape.com/documents/8828ab805e7291ab8eefa40c/w/b0610ef777c02531deccf1dd/e/85b079a3e0d9b2ab44e88f8e

The 2 faces are offset slightly that is the reason the revolutes will not work. The simplest thing to do is just use cylindrical mates for your last 2 mates.

Been working on the whole project for a few years now (on and off). I am going to CNC-mill the model in styrene to make the scale model.
