glued trim on 1974 duster

If you mean the one down the side, I just pulled it off of my 74 and used some paint thinner on a rag to get the stuff left behind off of the side.
Keep in mind I was going to paint my dart anyway so I wasn't concerned with not doing something to the original paint.
But it didn't hurt the paint and you couldn't tell the stripe was ever on there when I got done.
