What kind of glue did you use? You could try goof off or finger nail polish remover but make sure that you have good ventalation. I am not sure if it will hurt the leather or not. When I did my anniversary boot I had to drill four tiny holes and pop-rivet the new one on to get it to stay and look right. Paint the rivet heads satin black, throw on a mach 1 trim ring and the rivets disappear. Hope that this helps.
