headlights or lens needed for '09 Berkshire! Help

[pierce-FRF]

We have a 2009 Berkshire and it seems this was a transition year for FR where they used a one off Hella headlamp setup that is not readily available like most MH headlamos that are used from common cars.

Question is has anyone replaced their headlamps on a 2009 Berkshire and found what Lens or Fixture works?

thanks in advance
