Brake drum removal HELP

Try grinding the nail heads off the back of the backing plate that hold the shoes to the backing plate and take the brake shoes with it....

The hardware and spring kits come with replacements, so you're not ruining anything that you can't replace...
Don't know why one would disagree with this I was just about to suggest this. Sometimes you have to unbolt the wheel cylinder as well to give it a bit more "wiggle room
