Why did you remove the bumper guards?

I recently bought a '72 Dart Swinger which has the
OEM front bumper kissers.
The car came with a few extra goodies like the OE hub
caps and a new set of front bumper guards. I'm a "true to
as it came from Ma Mopar" guy so I may install the new
one's because I think they look good on a '72.
Then again I also like the clean look.
Ultimately I'll prolly sell both pair. IDK
