You will need another person and to jack the car up and place it on jackstands. Lift it high enough to be able to drill pilot holes from under the side blades. Also you need to have somebody hold the side blades up while you eye from above to make sure they are even wth the door when looking from above. Make sure you use your hands to check that the blades are correct front to back. Do not try to view if they are correct with the wheel wells as they can look off but are correct to the wheel well. Hard to explain but it is very hard to align by site front to back. Drill pilot holes and peel tape as you go. Easiest if you put a screw at the front then back and work towards the middle. Good luck as I said I was able to do it so anybody should LOL
