To get the shovel off it should be four bolts, I think they are 10mm. You can get to them without taking the tail section off. I don't remember if you have to take the tail section off or not to get to the wiring harness for the tag light.
To get the tailsection off there are two pushpins on each side on the under side. then the frankenstein bolts and the two small bolts towards the front of the tail section. It is easier to remove the tail if you take the small piece that is held in with the 4 push pins.
