umm ok ....
From the AD  "these are functional, but cannot be mounted
to a Firehawk - The prototype '98 Firehawk hood
had more material in the headlamp area to
accomodate the smaller encapsulated headlamps."
but in the picture, its a firehawk....
EDIT  ... further investigation it seems the hood that goes with them is "special".  So you buy the lights, but need to look for the "one of 3 prototype" hoods to go along with them.  I guess....
