e39 touring roofbars

[Scamp's Walker]

Just bought a pair on ebay. Genuine BMW with key but no instructions. Does anyone have a copy of the BMW fitting instructions that they could kindly scan and e-mail me,post details here or perhaps let me know where I can get a copy. I am sure that they are simple to attach....but guidance will come in useful! Apparently the front bar has fins and so presumably needs to go on the correct way round etc. Thanks in advance for you help.
