Just received a pair second hand, how do I fit them?

Cheers.

Did you get clips?

When I've fitted them for mates I pushed in at the top of the window and then flexed the front in slightly then push up.

If you have tinted windows don't use the clips.

Personally if it was me I would just use some double sided sticky foam where they actually sit in the window seal.

Your windows might not shut properly after but they will soon bed in.

Cheers mate.

Clips? Are they metal things?

I don't have tinted windows.

Yep the metal U shape style clips.

Good - just he wary if you get tints that the wind deflector clips can damage the tinting film.
