That's a question for a lawyer, but I'd say you would have no problems with it. I've seen it on a few cars over the years. I can do it for you if you like - I do custom paint. (I'm above Atlanta) As a side note, I have a factory rear spoiler & side window louvers for a '76 Roadrunner (same body as your Aspen). Very rare peices, never installed (NOS), need only painting to match your car & installing. The louvers came with windshield urethane-type sticky strips; you'll need to replace that (not too sticky after 28 years).
