Just talked to the engineer again. He said the rack he mentioned earlier is just a j-car rack.
He also explained that the reason we don't see racks with more travel than this is that it's not needed. The old worm gear systems (especially before power assist) needed long throws to provide the leverage necessary to turn vehicles at the time. Systems now don't require the leverage and therefore have shorter spindle arms and less total travel.
From the photo above you can see that "if you want" you could widen the window in the front of the Cavalier rack slightly to equal the mustangs original travel. Add Duane's crossmember and be done. Or just use the stock rack with no modifications and never notice the difference in turning radius.
And of course most of us have seen Randall's spindle modification to eliminate the problem.
