Use a putty and work around the edges. It's held on by double sided tape. There are alignment post on each end of the "burger" portion of the emblem that you will have to cut off to put it on the new grille. Walmart has some 3m extra heavy tape that works good.
fyi several people have had problems with the mr. grille causing a whistle. Someone put some screen door mesh behind it and got rid of the whistle. Just an fyi
Thanks for the feedback. I was looking at three grills...the Street Scene, MR Grill and Carriage Workls...of course I picked the one with the whistle..hopefuly this will not be the case but I apprecite the info
