Although I'm still busy figuring things out, it's actually it's not too bad. I was a little worried in the beginning because nothing was matching up correctly and the bumper was sitting out with a good 1.5" gap from where the bottom of the hatch sits while closed. Once I realized that some of the tabs are leftover from the casting mold, and not needed for fitment, it was a matter of using the Dremmel to file things down until it started to look right.
I still have a ways to go but it's definitely coming together.
