I just did my front and rear bowtie. The front is a pain in the arse and a two person operation. One person has to keep tension and the parts that get loose while the other keep fiddling with the clips behind it to get them off. I found this link, but didn't remove the top part of my grill to get to it. I just shoved my skinny ass arms in the hood lift section with a big flat head screw driver. It was a pain to get those center clips off. Anyway, for the rear one, I'd suggest doing what this guy did so you don't lose your spot.
