Put the box on for the x over and installed the ORD brace at the same time. When i went to install the splined thing that connects to the steering shaft ( the piece with the two bolts on it and the collar that keep the shaft locked to the box ) it wont fit. Were there different sizes and if so, how big of a difference? Are the splines the same and can i force the old one on the new box or will that fag it up?
