Not to be an @ss, but this has been discussed ad nasuem. The best thing to do is make it 'legal' so the shop can pass it. What you do after is up to you. I have the best luck taking it somewhere that knows me and my vehicles. I've got flares, mudflaps and whatever else I need to have it be legal. They may stay on all year or not, but as far as my shop knows, they can honestly say it was in their shop legal. Keeps them out of trouble with the UHP and puts the onus back on the owner of the vehicle.
They used to be available at Tera+ (Mepco) for a somewhat reasonable price. I've seen them on Ebay a little as well. I run 6" Xenon TJ flares on my 'YJ'. With my H1 wheels and full width axles, they are a pretty good match.
