This is a Firestik NGP antenna. I'll post the pics I was able to take, but I did start to close it back up before I started taking pics. The mount requires two holes, the top is 13/32 to accomodate an isolater and the bottom is 3/16. There is a rubber gasket on the outside and a large(r) backing plate on the inside. I have an over the driver bunk, so I lowered it and took out the trim covering the lift mechanism. I marked on the inside and drilled pilot holes from the inside out with the smallest bit I could find, just to mark where to drill from the outside. There is a pic of the trim boards where I came in behind. Once the mount was on I just ran everything down the A-pillar. I think it came out pretty nice.
