Looking for the best way to remove my "88 rear trans am decal and wanting to buy an original looking replacement.
goo gone and a rubber wheel on a drill is how I always did my modern cars never used this method on classics tho

 

You can try a heat gun on low, usually will loosen these up. Then goo gone for the residual adhesive.

 

The wheel would certainly work. As always, the method is only as good as the paint underneath. For something that small though, I'd use a plastic razor blade. I get 'em from my sign shop, but they're cheap on Amazon or wherever. I find uses for 'em around the house all the time. Then of course goo gone to clean up the residue.
