Its likely that there are quality rebuilders in every state. Check with your local auto parts store. They can put you in touch with far more services than they advertise. NAPA and Car Quest are two stores that come to mind.
As an alternative, and if you are interested in stepping up the level of performance, Check out Firm Feel in Seattle WA. Theres also Steer and Gear.(Not sure where they are located.... check a Mopar magazine I guess)
Finally.... your cars steering box is a common one, and finding a clean, used replacement is easy. ALMOST every rear wheel drive Mopar car through 1989 used the same basic unit. Save your Pitman arm though.
