Hey Mark

The king in the ad could of had the gauge cluster changed to a non corroded one, most clusters were made from inferior plastic which seems to deteriorate with time. I have had to change a few on some of my IIs.
The air dam if original sells for about 1600 used, and the air ducts are some of the hardest II parts to find. If that king has the air ducts still on the car then its a real King. Someone should email the seller and ask him a few questions. Kings are becoming the most coveted IIs to own, and with the popularity of the IIs on the rise, its only a matter of time before they start fetching outrageous prices.
