go and gull wings and later years??? 72-74

[1971roadrunner]

I know go wings were on 70 cars and gull wings were on 71's. On a b body there was no spoiler option from 72-74. Some could argue that go wings went on mid year 71 cars. There is alot of people who put wings on later year E bodies, most the time they look great but are they correct .Was there an option in 72-74 for a spoiler package on an E body or an A body?????
