Wasn't terribly difficult...be prepared to do a lot of sanding. Having a dremel helps a lot. Weedahoe has a video on the removal of the inner bezel from the larger piece. I recommend watching it. The plastic and gluing went fairly fast. Tip for the bondo, work quickly, do one side at a time then mix new bondo...sand sand and more sand. The painting too the most time for me..but I did this all in a day. The install is a bear because you have to cut some of the inner plastic to get it to fit...if you cut carefully, you can let the plastic support the weight of the radio
