Uneven tie rods and adjusters? Steering wheel alignment weirdness

The tie rod adjusters should be very close to the same length, and the master spline on the steering shaft should be centered. You can set the toe correctly and have the adjusters be unequal if the steering box is not centered.

Your aftermarket steering wheel adapter may not work correctly with the master spline on the steering shaft, so that may be a separate deal. The more important thing is to get the steering box centered and the tie rods close to equal length.

So, center the steering box so the steering gear is in the middle of its range of travel. There should be a small "on center" spot that is obvious when you center the box. Don't worry about where the wheels point when you do that, your adjusters aren't equal so they won't be straight. Once the steering box is centered, adjust the tie rods so the wheels point straight ahead and then set the toe. When that's done the steering wheel itself should be centered, but again that may be a separate issue with that aftermarket adapter.
