I am needing to undo the rivets in both my cars to lower the hood latch for the new hoods, remove the stock Ebrake handle assembly from my Cobra to replace it with a 99+ Dark Charcoal one, and some other things that are held in with rivets. However, I have never done this before. How do I remove the old rivets? Where do I get new rivets? How do I put them in?
