Yeah, I have various mic's but in this instance I just used a very cheap lapel microphone, like this:

Just zip-tied it to the offending end (I did both sides), ran it into my video camera, drove around for a few mins and listened to the results on the computer afterwards. (yes, I used to be a sound engineer/producer )
Haha abit technical for me
Ill have to investigate. I noticed thqt link you sent was not from the uk. Did you have to import yours then or can i get them from the uk. Obviously nissan should supply them at an expensive price??
