From what i saw on their website, it basically looked like minor trimming. I don't consider using a sawsall minor trimming. Tin snips are minor trimming. You have to cut the upper most fender bolt mounting tab. No big deal. You have to cut off the ends of the plastic cowl which includes the only 2 screw mounts to hold it down---they go away. Then comes the hinge bracket. My truck had a bend in it the way it was made. Website made it look like it was straight & just slipped in. Mine did not. It would not fit because of said bend. Also, the part of it, with the mounting hole, has to be on the inside of the mount. No way, no how would it work without cutting. So, I had to make a cut under the mounting hole & far enough back so the mounting hole became a tab, that could be bent over to go to the inside. Also, the bend had to be cut out in order for it to work & far enough back, so the I could cut down into it from the other cut & remove it. There just is NOT a lot of room to do this with a sawsall. Maybe a air saw would be better, IDK ? You also have to trim the fender up top, to be able to get a wrench on the nut once you actually install & tighten things down. Then to top it all off, they did NOT include the hardware !

The ONLY hardware that came with it were the nut & bolt for the L bracket. Nothing for the mount to the part I had to cut up. A trip to the hardware store & $4 later, I was set. Also, there were NO instructions included. I had to keep coming back into the house to look on the computer. THAT SUCKED as well. Now that they are on, they seem strong, but would be MUCH stronger yet if they drilled a hole in the flat part that rests under the hinge & included a flat top hex bolt to go in it. I may do that in the future before I actually mount the lights. I don't have the lights yet. Buy some sawblades before the job. I bent the shit out of mine 4x but was able to re straighten it enough to finish the job without breaking. Just not enough room for the stroke of the saw.
