Keep in mind that most factory setups using this style of steering (draglink connected to the tierod) did not have to contend with leaf spring interference. Jeeps were either spring under so the tierod was already above the springs or had coils, the early Ford F-150s and Broncos were also coil sprung so on leaf springs. This allows the draglink end to be very close to the passenger tire and helps eliminate the angle. All of these vehicles also had panhard bars that were set to really close to the same angle as the draglink to avoid bumpsteer issues.
With the relatively narrow spring spacing of this era GM trucks and the spring over suspension the draglink would have to attach to the tierod much further away from the tire (towards the center of the vehicle) to provide enough clearance of the passenger side leaf when turning to the right. And since you can't put too much drop in the pitman arm (it would hit the driver's side spring plate) there would be a pretty substantial angle on the draglink causing crazy bumpsteer and the other associated downward stresses on the draglink and tierod mentioned above.
Not saying it wouldn't work at all, but it is far from optimum and thus the reason it is not the common solution used.

ofcourse, that's likely still needing cross over tho. I like that the knuckle is ready for the drag link to go over the spring tho!
