Cody, That Shaft is collapsable. When I convert from manual to power steering, I colapse that shaft to make room for the longer power box, then change the coulper to the finer spline one. Just pull it back out and you are okay. Just make sure that you have a good small pin that keeps the joints inside the coupler, under the seal and cal. ALWAYS work that coupler onto the splined shaft by hand. It should slide easily onto it before you drive the big pin back in.
