67 yenko emblem placement?

[Supercar_Kid]

I am curious about the process Yenko mechanics may have used to remove the factory engine indentifications from the front fenders of the '67 cars. I doubt they'd be too interested in removing inner/outer fenders to access the factory speed nuts, but aside from trying to break the pins off the castings with vise grips or some other hack master method that's about the only choice. I'm assuming any new badging would have been attached using "push clips." Any thoughts, experiences?
