I have a 72 GMC half ton pickup with a bit of steering wandering. I have replaced the ball joints and tie-rod ends and even had it aligned. Then I found a great deal on 33x12x16's I couldn't pass up. Now the steering box is leaking. I believe it's the original box so I just bought a new one. The question I have is how to replace the steering shaft. I have some play in mine and Flaming River and Borgeson only go back to '73. Is there a way to adapt a shaft for a newer model to the 72 and get rid of the rag joint? Any help would be appreciated.
