1971 Challenger grill paint?

Hello,
I am in the process of restoring a 1971 Challenger grill. The grill has the light silver rough argent paint due to it being a RH model. I like the look of the dark / black paint used on the R/T models. I can't remember if the R/T grill paint had a smooth paint texture or was a dark / black argent rough finish? If it is a rough dark / black argent finish, where can I buy this paint in rattle cans? I check out Herbs and Roseville Moparts, They are either out of stock or not...
