The original lavatory sink faucet in our '77 RK model deteriorated to where a replacement was necessary. I replaced it with a slightly larger bar sink fixture with 4 inch spacing between the inlets. This required installation of brass adaptors to match the water line connections to the faucet. These were readily available at our local plumbing supply. The best part of the job was finding out that the entire sink cabinet can be removed by simply backing out two screws at the left rear corner inside the cabinet plus two more at the front right corner, leaving the sink in place. This gives easy access to the water connections.
