Late 70s, early 80s "must haves"

im transforming my 72 440 duster into a late 70s street freak, slot mags tires sticking out the quarters, yellow plug wires, speed stickers in the quarter windows, etc...

what other "must haves" was the mopar crowd doing in the late 70s early 80s? share pics ideas, anything goes as long as it would be "period correct" for the time
