Just installed these with my 70 cross member. Problem is earlier trucks used a round concave washer behind the control arm shaft that matches the convex area around the studs for caster adjustment. 73 and up use a washer that is flat on the back side and curved on the control arm side to match the control arm. If you install both washers you have too much positive camber without any shims.
