What you need to get is a vl section with all the unis and the same spline that fits into the end of your vk steering column and the piece that then connects the vn rack to the vl steering spline.
I probably have not explaned that well but you need the lower end of a vl steering column that pokes through the fire wall and fits up to the vn rack. all leagal and bolts together. You need to pull the steering column out to change it over.
You are at about the same stage I am doing my vb conversion.
