Im getting ready to paint the shaker bubble on my 70 challenger... I plan on painting it the same color as the car (EK2- GO MANGO) I was wondering if the shaker grill inserts get painted the same color as the bubble or are they black? I see that the promo EK2 six pack chally's shaker grills are colored the same as the bubble..Not sure if they changed it along the evolution of production.... thanks!
