It's not that critical. The whole idea of the drag link is to be articulated. Down angle from the steering box will help throw steering off all the more in more extreme angles. I couldn't tell you if any of my trucks had the drag link parallel with thr ground or springs. The ideal set-up is the drag link laying in line with both the steering arm and pitman arm. Depending on what springs you have, they can be negative arch to extreme positive. In all cases the idea geometry is straight in line with both ends.

I did a 4" lift on my '72 and used a 4" raised steering arm and it looks to me like the drag link runs uphill to the axle, as if it would have been just as off in the other direction if I left the stock arm on. They say springs can start off higher when new. If that's true, the angle will get worse and I'd be closer to in line with stock arm. The stock springs were so sagged I only had about an inch to the bump stops. I'm not too worried about it. I've driven them all different ways and did lifts before anyone ever thought about compensating the drag link angle. I feel they all steered the same. They say no drop arm is needed for 2-3" lift, so whatcha gonna?
