My boss and I replaced my steering gear box on the clipper the other week. I had bought the replacement from O'Reilly's, and when we got it installed, we realized that there was a chip on the intake. I went back to O'Reilly's and they waranteed it out and gave me a replacement. At that point, my boss realized he would have to take the one out again and put the new one in - and it took a lot of work getting the one in (and a bruised elbow). So, he decided to just file down the intake instead.
So, I now have a new remanufactured steering gear box for a 1975 360 engine if anyone is interested. I will bring it to the rally next week.
