new drag link install ??

[67gmcstepside]

I just recieved my new adjustable steering drag link and not sure if the smaller drag link goes to the pitman arm on the steering box or to the axle.

Second. I assume that I center the front tires equal front and back and tighten down the adjustments then center the steering box with equal turns right and left the adjust the drag link accordingly and bolt her on??

Thanks
