So i'm looking to get new tie-rods (ends or whole rod kit) for the Beam front end. It's a complete take-off beam from below the equator.. with disc brake spindles and the spring torsion adjusters -- so Ghia type beam? Looking on websites & there are pre and post '68 versions. I'm guessing with the disc spindles, I go with post '68, but looking for a little confirmation from the experts. anyone know the difference?
