I HAVE A 2003 F250 7.3L. I JUST PURCHASED A SET OF 99-04 HARLEY HEADLIGHTS AND THE PAGE SAYS SLIGHT MODIFICATION REQUIRED. I WAS WONDERING WHAT MODS NEED TO BE DONE. IF ANYONE CAN EXPLAIN OR IF SOMEONE HAS A LINK I WOULD APPRECIATE IT.
THANKS
JIMMY

 

Are they one piece units like the 05 up including the signals? If so yes the header panel has to be cut, or replaced.

 

YES ONE PEICE HEADLIGHTS. IS THERE A LINK THAT YOU KNOW ABOUT?

 

Here is a PDF of a write-up.
