I have just finished replacing the original Gray Industries plastic ports with New Found brass ports. I am offering the old ports, or parts there of, for free, plus shipping. The old ports are the standard 5 x 12 and 7 x 15 (4 of each) for the h27 and are in poor shape. Most have at least 1 crack, but none leaked at the time of removal. I have not cleaned the old ports yet, but will hold them in my garage until April 15, 2019 to see if there is any interest; if no interest they will go to the dump. You may contact me directly at amcmahon@ec.rr.com if interested. Below is pic of new ports in Radiant Beam.
