What emblems? where on the body? 99% of them use 3/8" (head) speed nuts on the back side, which means you have to get to them. If you're talking about the ones on the sides of the fenders, you'll have to drop the inner fender wheels. Not all that tough to do.
If you have skinny enough arms, this can be done through the door jamb. Be patient and make sure you tie a string to the end of your wrench because you definitely will drop it inside the fender. You'll probably lose a few of the nuts, but that's not a problem.
