Are you talking about the Dorman rebuild kit for the little box on top of the steering box? Dorman 425-253? They're ok.... Not the best, but certainly better than living with the slop the water soaked, rust boxes start getting..... If you have a boneyard nearby, you might consider modifying a steering rod off a 95-97 to fit your old beast.... I usually get 'em pretty cheap....
Nope. The steering shaft itself. Looks like a slightly beefier version of the OEM unit. Dorman talks about needle bearings etc on their site.
