I did the same.Replaced my front and back gold bowties with black bowties.
Unfortunately - getting the tabs free for the front bowtie was a problem for me and I ended up breaking all of them off
Tried super glue repair which I thought might work but when attempting to install the black OEM replacement badge, they just broke again.
Three of them in and under the radiator I believe.
How hard is it to remove a front lower panel to look for these?
Replacing the front upper grill now...expensive mistake.
