You can even do the paper clip trick to secure them so you don't use screws. Easy to take on and off. Can't think of the exact name of the clips, the ones that are black. Been thinking of doing this when I get the car out this spring.
Thanks for the replies. I guess it is a good investment. The look is cheesy but a cheap fix to save the paint. Just curious, can someone explain the binder clip trick?
There really isn't a trick. You place the rear flaps where they need to be and use the binder clip to attach them to the lip of the wheel well. This holds them right in place and saves you from having to drill into the lip for screws.
