Do some extensive testing of the toe change as the steering moves from center to full travel in both directions. Changing the distance from the tie rod end pivot point to the brake backing plate will have a major effect on the Ackerman angle. If you get it wrong, the vehicle will have very unpredictable handling in turns.

Edit: After doing some research in some old training material I used to use while teaching steering fundamentals, I found a diagram showing a method for finding bent steering arms. It might apply in your situation. Stretch a string from the kingpin pivot point to the center of the rear axle on both sides. With the wheels pointed exactly straight ahead, the steering arm tie rod end hole should intersect the line from front to rear on both sides. On an independent suspension system, the lower ball joint will be the front pivot point you're looking for. Good luck!
