mine is 1/4" larger gap on one side than the other. I'd have to shift the body by half that amount , or 1/8", to get the body alignment centered over the rear axle.. You can see how impractical that would be at the factory.
When I lift the body to install the "#5 GNX" bushing in rear, a gentle shove should center it.
