I'm looking to purchase a wind deflector for my 2004 C70.

Somewhere I read that there were two different mounting types depending on the year, but I don't recall where I read that.

I have round holes (approx 3/8" diameter) under the rear windows. The one I was looking to purchase was from a 2002 and looks like it has a flat bar. Did Volvo change the mounting hole at some point from flat to round?

 

The round holes are the current design. I changed mine from the flat to the round. I am not sure if I saved the the old ones.... They can be purchased from Volvo.
