Avant boot struts - same across B6, B7 and B8?

[munchkincoupe]

I replaced the boot struts on my A4 B6 avant with some aftermarket ones from ebay as my OEM ones were leaking. They don't lift evenly or at the same rate so I want to put OEM parts back on which I believe are part number 8E9 827 552 - would used ones from a B7 or B8 avant also be the same part number?

Thanks
