Remove the fenders and sometimes you can push them out by hand, if not you can lay it over a bag of sand and gently tap them out with a ball peen hammer.
Sometimes, but this will discolor the chrome, you can heat it up really hot with torch and use some dried ice to pop it out. I see that done a lot but again, it'll discolor the chrome.
Geez, Walker...always in it for a sale Good for you.
As for dents it helps if you have the correct matching radius otherwise you'll make a mess
on the outside. Gooood Luck :roll:
