Painted Stripe Removal

I found a 73 duster on craigslist for sale that I'm really interested in. Husband and wife inherited it after her dad died, they don't know too much about the car, but they believe it to be original paint. Engine bay looks to have been repainted at one time. Someone removed the factory stripe and painted one on.

What can I do to remove this paint? I don't want to mess up the original paint, but I want to go back to a vinyl stripe if I pick up this car. The painted stripe kind of ruins it for me.

In order to eliminate the stripe you would have to repaint the car. Graphics like that have to be sanded to bare metal and primed or they will be seen if repainted.
The paint on the car looks like it is in good condition. Unless you absolutely hate the color scheme, leave it be.
