man, I don't know...I'll leave it up to my body shop...he's very good, but I don't want to have to do that kind of thing to my car...in order to make them work...they should've been close...they obviously didn't hold shape when taken out of the molds...there could have been a lot things that caused that...just have to wait until I see them I guess...but I won't put on something that looks like a cheap bolt on...or stressed to point they want to break the fastener holding them on...skirts take a lot of hits when running in the rain and such....let alone the stress of the car flexing, even though it doesn't flex much, it still moves...
