If all I've read has been correct, there is one difference.. The shimming for the motor mounts to the frame. I know some people have complained of a gap found between the frame and the motor when loosening motor mounts on the 08, but I thought I had recalled someone stating that they checked their 09 and didn't see the issue.
Am I wrong? Just thinking out loud :-)
