Thanks - I just didn't see any mod needed from the info here, and the candlepowerinc site didn't show any modification needed. I did get a reply from them.
"On any vehicle that originally takes H11, you need to shave a small ridge of plastic off the H9 bulb's connector so that the H11 socket will snap on. This can be achieved with an X-acto knife, Dremel tool, or other suitable tool.
