There's not a lot to them mate. They come with full instructions
The stock antenna screws off. The shark fin comes with it's own screw and washer
Use some prepsol or similar wax and grease remover to wipe around the base of the antenna roughly where the shark fin will stick to the roof. Make sure the area is free of dirt and waxes etc that can hamper the shark fin adhering to the roof
Use a screwdriver to attach the shark fin antenna. Don't remove the paper from the double sided tape yet. Place the shark fin on the roof and work on positioning it so it's centered. It's easier if you have two people here but it can be done with one person.
Make small adjustments on the aharkfin position until you're happy it's centered on the roof. Use masking tapeto mark the position of the shark fin without disturbing it
Once marked you can lift up the shark fin, remove the paper from the double sided tape and carefully replace the shark fin using your tape markers as a guide.
I've found holding it on an angle and placing the rear of the shark fin on the roof first lightly allows you to make small adjustments without the fin being too stuck to the paint.
Once you're happy, lower the front so it's just lightly resting on the paint and double check your placement.
If you're happy, then push down and hold it for about a min to let it bond
Done. Stand back and admire your handiwork
