As for the work that needs to be done to the Silvy Hood to get it to fit the Yukon Headlights. Study the pictures I have up already about the cut. The red line is where I wanted the hood to end, but you must cut about 1/2 inch long on the outer shell to be able to fold it back using first a pair of flat nose pliers to get the break you want and then a hammer and dolly with the proper shapes to hammer it to where you want it. The inside shell, needs to be cut to the correct length to meet up with the folded in portion. If it's you first time doing something like this do it very slowly and with patience. You can always hammer or cut a little more, but fixing a mistake can take much longer then doing it slowly.
Just a note for those of you considering this, I noticed that once you cut away the headlight portion, the hood edge appears shorter than the rest, and is sitting almost directly above the top seem of the headlight lens and housing. To rectify this I elongated the holes in the hood bracket allowing the hood to be pulled 1/4"-1/2" forward.
