I don't think it will come very close to lining up. My buddy's dad had a '91 W250 that he wanted a B&W for. He couldn't find one so he bought just the center part with the ball and reciever and modified it to fit between the frame rails. It attached with homemade 1/4" side plates similar to the ones B&W uses. From the outside, it looked like any other B&W. You had to look close to see the homemade part.
