Thanks, Ive taken the shroud off and looks as though the hood latch is going to be in the way too. I did buy that one from hammerhead. Thanks for the adviceI'm betting you bought the badge from hamRheadCreations on Etsy? I was one of his guinea pigs with the 2014 badge on the 2015, I ended up pulling the studs and attaching it with 3M double-sided tape since the stud patterns are different. So can't say how easy it is to attach the nuts to the studs when installing the 2015 badge.
Removing the old badge is pretty easy, first remove the radiator shroud. Just take a flat head screw driver and pry up the plastic pins that hold it in place. They will pop up with a lil force.
Once the shroud is removed reach behind the badge and break off the studs, you could just pry the badge off from the front but this way is easier and should avoid any accidental damage.
After that it should be as simple as threading on the nuts on the studs. But I have heard that you may need to remove the hood latch to get to the stud in the middle of the new emblem.
Hope this helps.
