Timothale is right about the Ackerman, Sunbeam Tigers used to have the same problem when they put the rear steer arms on the front... the inner wheel would aim away,(toe in), from the corner in turns
You need that inner wheel to have more toe out on turns
Also, it looks like you need to get a shorter rack, as the inner pivots look to be outboard of the lower control arm pivot.
The inner tie rod end needs to be centered on an imaginary line drawn through the lower control arm inner pivot and the upper control arm inner pivot.
Otherwise you will have bumpsteer.
And yes, like AntnyL, has stated, you definately need a couple of gussets going back into the crossmember or frame at the lower a arm pivot..
That piece of 3" rectangle will twist off fairly quickly from the fatigue of braking and road irregularities..
You may have already fixed these issues, but that's what I see in the pictures.
Looks good though..better than a MII
