I’ve looked at them six ways to Sunday and it’s really hard to tell in photos. The instructions show they should be installed convex side forward. I think he’s got them right.
The place I went has a $99 minimum but they cut me a deal at $75. I think it would normally be about half that but since they blast and coat I am fine with paying extra. Harley doesn't make them so I have to do what I have to do.
So the ones in the picture are backwards. The little lip on them faces forward.
the chrome is not as shiny on the backside of these. I am confident that the ones pictured are installed the correct way. The diagram above definitely shows that the opposite direction though.
