radiator support blackout

Hi , on my 71 the rad support is painted the same colour as the car, can someone post a good picture of how far you should go with the flat black paint behind the grill, and should it be semi gloss or flat? Thanks.

Yes they did.
Take a look at the boxes with the notes at the bottom right. See the FG /BJ?
F & G are the series (model year) F is 1970 & G is 1971.
B is Barracuda & J is Challenger.
