What I did was get the winch extensions from Ablinn and then took some 1/4 plate and bent it to look like the original bumper then milled in the slotts for the cable and shackles then bolted 1/4 plate to the bottom of the winch extensions that the winch mount mounts to. I will be welding the 1/4 plate to the winch extensions to make sure it doesnt move and it should be good. It looks ok, I would center the cable slot better the next time but it works. You can see it at the URL below. I cant remember what the winch extensions cost but the 1/4 plate was about $30.00 from a metal shop and I have access to a mechine shop so that part was free. It took about 3 hours from start to finish to make it all.
