power steering box hitting the frame on 64 C10

[allaboutchevelles]

Took a half day vacation today and came home to work on the truck. I stuck the steering column in and cut the end of it off. I bought the power steering conversion kit from CPP. I mounted the new plate onto the frame and then mounted the steering box to it from a donor 72 C10. Everything lines up good except the side of the steering box is hitting the frame and not mating up to the plate all the way, about an 1/8 inch gap in the front. Anyone else had problems with the box hitting the frame??? thinking maybe a thick washer will do the trick??
