All NEW Ports installed

I am gonna guess that the Bomar ports originally installed in 1980 were the cheapest things on the market at the time.  They have mostly stood the test of time.  Except they are 'crazed' cracked and leaking now.  So i have replaced all the ports with NEW stainless steel models from New Found Metals. These are very heavy duty.  i got new bug screens for each port and also got Peekaboo window treatments throughout.  *can YOU spot the old and new?
