On the Lippert Trailair Air Ride 5th Wheel King Pin, # LC179879, king pin center to the first row of mounting bolt holes measures 9 inches, center king pin to last row of mounting bolt holes measures 16-7/8 inches.

If you look at the diagram I provided, you can see the other relevant measurements for this replacement king pin.
