I know this is an old thread, but... I just installed an aftermaket LED assembly from an '05 on my '07. OEM may be a little different, but here's my findings:
1. The Park/Turn/Brake uses the same socket.
2. The Reverse uses a different socket. That required some work to get a functional reverse light!
3. The mounting screws are in a different location. In my case, I had to shave down what appeared to be an alternate location for the screws and glue the mounting screws in place (seems to be holding well after a couple of weeks).
