BTW... if you look at the drawing of the badge and the grill - you will notice that there are three 'centering pegs' that are used to keep make sure your badge sits centered into the grill assembly (you probably have these pegs on your new emblem as well)
if you heat up the current badge with a hair-dryer and try to peel it away from its current placement, you run a very high chance of snapping these fragile centering pegs... then you may have wished that you too had gone with my (B) suggestion
..i've been there
...i've done it before
i just hope that rather than learning from your own costly mistakes, learn from other's mistakes...
