Ha! I keep thinking I have this figured out. Well, the ad says they came off an X5. I see that there are a number of X5's, so I will ask this question. Is the e53 just the 2000 to 2006 models? I think I'd better ask the seller for the part number.
I will post the link below, and maybe you can take a look. There is also a set of style 99's that came directly off a 4.6is. That would be more of a sure thing, but i like the 69's better, and they are in a better location for me to be able to get them.
