That's definately a 73-87 front axle and steering box as well.
I can see that it is lifted by the amount of leafs on the springs.
If that truck has a 6 inch lift and still has the stock steering arm , you need to change it.
There is a special steering arm available for 73-87 chevy trucks with 6inch & higher lift kits to correct this problem. i just remembered about this.
The arm curves up higher and levels out the drag link the way its suppose to sit.
On right turns the amount of tuns from center to lock changes which doesnt allow the pitman arm to move away from the wheel.
Rancho suspension sells these& just about all the other suspension companys have them too.
Im almost positive this is your problem.
