The only way you could get factory fitted twin headlight front was if it was either a Sandman or B06. All the rest is a option on any van or Ute.
There are too many things wrong in my opinion. Too many things changed and it will always be questionable if HHS can’t confirm it.
The front could have been dealer fitted, but why would they when you could just order a Sandman? More likely fitted when they fitted the WB doors and GTS guards.
