I've just taken a couple of measurements. In the straight ahead position, which is where the drag link is vertical and at its lowest point and contact would be the worst , the distance from the ball joint at the front of the drag link to where it crosses the tie rod is about 7" and the drag link is about 21" That means that for every 1/2" clearance between the drag link and tie rod, the car at the steering box has to come up 1 1/2". Given that the steering box is not at the front of the car, I estimate that resetting or replacing the front spring will have to raise the front cross member by about 2" The ratios change, of course when the wheels are turned but I'm sure you get the idea.
I suggest a new spring and if there is still too much intimacy between the two, try bending the arm at the front of the drag link up a little.
Just say'in!
