Sorry. It's a 1955 series 2. However, it has a Chevy 350 in it. After reading the manual again, I'm not sure if I can even pull the steering column and box out without taking the headers off. The steering box is mounted to the inside of the frame but I can't see any way of getting the column off easily. I'm afraid this is beyond my expertise and am also worried it may be too expensive to have someone do it for me. But it's evident that it's leaking oil badly.
