I had a divorced power unit on a 67 nova wagon. They are still available from Chevy II parts suppliers. Way cheaper than Corvette parts. If I remember, the cylinder is ~$100, and the actuator is about he same. You'll also need a different pitman arm that will accept the actuator ball joint.

I would never put one on a vehicle again. The actuator depends on you moving the stearing wheel a little bit, then it adds power to the cylinder. I found that this led to real problems on the highway. Bump the wheel just a little, and you were in the next lane. If purity is what you want, stay manual. If convenience is what you want, put on an integrated power steering box. It may be that you can't have it both ways on your 4x4. my.02
