My wagon is like that too. Right front sticks out more and the left rear sticks out more. I know it's there just from working on the thing so much, but no one else has ever said anything. It doesn't bother me since this is a beater.
It's also possible that the frame is suffering from middle-age spread or sag. Sometimes the upper control arm mounts move in relation to each other as the car ages/goes flying over speed bumps/etc. The crossmember is not as stout as you might think, and like I said, it isn't unusual to see some change over time. It's more common in unitized construction (think Fox Mustang, and all those tower braces), but does happen in frame cars as well.
Point being, if one side needed a bunch more shims to achieve caster/camber within the desired range, that could account for SOME of the difference side to side,
FWIW, my 81 wagon is like that as well
Awesome. Thank you for this. This well help me narrow it down.If thre body and frame are aligned have you checked for any indication the front clip on the frame has been hit? If you measure the x for the front clip in the diagram that will tell you if the frame has been twisted
The difference is a little over 3/4 of an inch. I did see they have offset upper control arm shafts to help with the scenario you described.
