In case anyone's wondering what the F we're talking about...
The KFI winch mount comes with carriage bolts that you can run through from the inside to attach your fairlead.
That works great for roller fairleads, but hause fairleads are shaped differently, and you may not be able to stick a nut on the other side to attach to the carriage bolt.
So you may need to put a bolt in from the front and put a locknut on the back.
But the bolts that came with your fairlead are probably 3/4" long, which is usually fine for the thickness of the fairlead plus the mounting plate.
However, the KFI mount also has a brush plate in there adding 1/8" thickness.
That means once the bolt goes through all layers of material, there is not enough thread left to engage the nylon part of the locknut.
So you need a longer nut/bolt setup, and the tricky part is that your socket might not fit down into the hole that the bolt goes into in the fairlead.
