Hope you keep this thread updated. If you can, I'd like to more on how you determined "no bump steer." I'm guessing? the rack is considerably ahead? of where the original center link was?
With this being a front steer setup, the tie rods move to the front. The width of the inner ends of the Rack will determine where to put the outer tie rod ends to achieve good bump steer, and as I posted above, with the unequal upper/lower control arms, the needed tie rod length gets real long which puts the ends way out board of where I would like. That is why I would go with a four inch narrower rack to start with. It would also place everything closer to proper Ackerman angle, which is the outer tie rod, lower ball joint, and rear axle center line all on a straight line.
