I'm pretty happy they don't have 6. 7 on them!
Not sure how they are attached on your 4. 5. On the 2010, they are glued on. I used fishing line to cut through the foam adhesive while at the same time used a plastic body filler spreader to help seperate the emblem from the body. After the emblem was off I used a rubber eraser wheel, for removing stripes or decals from paint (sold at NAPA). The wheel goes on a drill and makes short work of cleaning off the adhesive without damaging the paint. Sorry I didn't take pics.
