Or does it go under that sheet metal cone attached to the backing plate?

Those go on the inside of the drum. Your old ones may still be there, hidden amongdst the muck. There will be an inner wheel bearing located behind it.
Clean up the area first, and you will find a large snapring retaining the seal. Remove the snapring with a large screwdriver. If the snapring doesn't want to move, you may have to give a slight tap to the old seal to move it away from the snapring.
Now, with a long brass drift, hammer the inside cone of the bearing from the outside of the drum. Be careful not to hit the metal cage that holds the little rollers in place. work around the inside edge until the seal pops out. The bearing will now fall out.
Clean the inside of the drum, the snapring, and the bearings with solvent. They should be spotless.
Once you have the brake drum turned or sanded or whatever you decide to do, Pack the bearings with grease, and place the inside bearing back into the hub. Your inner wheel seals are leather and should be soaked in oil for a half hour before installing them. Ideally, you would use a seal installer or a large pice of pipe that fits to the outer edge of the seal. That way you don't distort the seal. But if you don't have those, you can usually get away with a light hammer and a brass drift. Punch the seal in just past the snap ring, then install the snap ring. Now, with a clean drift, knock the seal back out so it is against the snap ring.
Clean out the inside of the metal cone attahced to the backing plate, and also clean out the little pee hole at the bottom of the cone. This will allow any oil or grease that do sneak past the seal to go outside of the drums and away from the shoes.
Carefull when installing the drum onto the spindle that you don't hit or distort the seal. Install the outer bearing, and then the first adjusting nut. Do not overtighten the bearings...you will end up siezing them. Follow the manual for the adjustment of the bearing.
