Rack not going all the way to one side.

[tayloray]

So i had my buddy mod my Knuckles, and I always noticed it steered further one way then the other, after the knuckles, we noticed the steering rack goes farther to one side than the other. if you measure from the edge of the rack housing, to where the inner tie rod threads in, one side is around 5 and 5/8th's " the other is about 4 and 1/4.

Any clue what this could be?
