They just bolt on fella
.
There are the bolts you can see along the top of the wing plus another 2 behind the door and 2 more at the bottom of the wing under the sill, YOU WILL NEED TO SOAK THESE ONE'S FOR A COUPLE OF DAY'S WITH WD40 AS THERE WILL BRAKE OTHERWISE AND STILL MAY DO EVEN IF YOU SOAK THEM
.
Also you will need to remove the front flasher as I think there is a bolt there also
I hope this helps you fella
