Bought mine on Amazon. https://a.co/d/19VVFKr
OEM part was way more than I was willing to pay so I'm taking my chances with a Chinese replacement. Working fine so far.
I did the same thing! Just replaced the steering box but it would only turn right. After I thought about it a little bit I figured it out. Any idea what the torque specs for the pitman arm nut and the tie rod nut is?
