Yeah? Let's talk. Your photos look great. Interestingly enough, the dimensions on my winch are different from the ones in the 8274 thread. Take a look at photos here:

Maybe the spacing changed as Warn modified the winch; the vertical spacing on my winch is 4.5", but the horizontal is 11.5" and 13". There's some game to be played to get a standard 10" fairlead to fit - I'm guessing that the driver's side end should share a common bolt with the bottom winch bolt on that end, but the fairlead gets its own bolt at the other end. (I'm going to use a standard fairlead, aluminum, with synthetic winch rope - if I have to radius the inside edge of the fairlead, so be it.)
I've had several go-rounds with the CCOT folks, and they seem uninterested in doing anything custom - I offered to send them a fitted winch plate to be welded to one of their bumpers and then all powdercoated, but got nowhere.
I really do intend to make up a .dxf file for the winch plate and try running it on the CNC plasma cutter. That thing is wicked cool

I'm learning to weld, but I don't think I want my first job to be a bumper that I'm going to yank on in an emergency. Sounds like you don't need the winch plate, either.
The existing bumper is a complete butcher job - someone
welded some C section to the gusset plates on top and the side brackets on the bottom. I have new side brackets and already put light tabs on, also have new gusset plates and hardware. (So, yes, I will have to cut those PITA rivets off.)
