why do people help make old cars look bad

serious question? what is the correct color for my 71 duster's grill?? it is sorta blackish looking right now with Texas mold here and there.

I like seeing non factory changes to these old cars that CAN be changed back by the next owner. he could put back a chrome bumper etc...

yep Demons are hard to find and their specific parts are too! seems to me.
