i don't think 1967 trucks came with power steering as an option and becuase of that the did not have an indent in the frame that is required to mount a PS box. I think the PS boxes have a little more "bulge" in them. I've seen people use small spacers to move the box about 1/2 inch away from the frame and i've seen people take a torch to the frame to form the indent. Not sure which route is safer. An 87 box should have the same basic bolt pattern.
