71 Demon hood bezels - black or chrome or with/without 340 emblems

This is my second H code 340 Demon and not sure what is correct for the hood scoop bezels for 71?

I have seen black; I've seen chrome and I have seen both with the 340 emblems.


I've been looking at pics on the net and looking for factory drawings to no avail.

I saw this Demon ad from 71 and it shows a black bezel with no 340 emblems, but not sure if this was a pilot car or prototype?

Then I saw this car from BJ auction with the chrome scoop and emblems/

Anyone have any factual data they can share please?

TIA!
