I am making 2 Camel Trophy style winch boxes. They are for Discovery 1's and mount very far in requiring a trim to the grill. They may also work for RR Classics. I have the parts drawn in CAD and will post renderings tomorrow. I am having the pieces laser or plasma cut. 

I would be happy to make as many sets as there is demand for. The more I have made the lower the price for each set. These will be unpainted steel "weld your own" kits. 

The bottom plates will have no holes as there are many winch patterns. I will have the laser cutter put divots in all the patterns I can find so it will be easy to drill the mount pattern on the drill press or even with a hand drill.

 Here is the box. As there are a few winch mount hole patterns the bottom plate will come with divots where the different  hole patterns may be. You the end user will chose the hole locations you need and drill them with a drill press or hand drill.  The divots make easy starting locations.

 Here is a rendering of the final hole layout. This will accomodate Warn, Mile Marker, and any other winch with a 10 x 4.5 spacing. 

Won't fit Hydraulic Mile Marker. They have motor on the opposite side. What's the purpose of those small extra plates on the sides and between winch and fair-lead. Seems like unnecessary extra expense! Keep it simple less cutting == less $$$

 Here are some pictures. One is a clumsy depiction of where the side plates mount to the frame. It is not as simple as displacing the cooler lines the cooler its self has to go up a little. The second picture shows where I plan to cut the cooler lines to move it up.

Hopefully Todd will chime in here. He's gone through this already. I think he wound up with braided lines after first trying a soft line.

I threw my hands up in disgust and took it to Columbia Rovers. I'll have to see what finally held next time i'm there.

I had a hard time getting the rubber hoses and hose clamps to hold.

They are not low pressure lines. I found that out the hard way...

I had a LR Auto box ad had all kinds of issues with the cooler lines, not just the grill cooler, but also replacing the under vehicle lines to the cooler.  separate incidents but troubling all the same.
