Mud flap installation problem

I dont know why, but I’m having problems figuring out how to install my rear mud flaps back onto my car. I took them off because I dumped the car and they scraped. 3 years later I’m raising it and cant seem to get anything to line up ill take pics later not sure if they’ll help. (searched mud flap but came up with FS threads only)

pics?

you just use a phillips and screw 3 bolts on.

There are two metal clips that go one the bumper an a plastic one that goes in the wheel well if you didnt have those then you cant get them to screw in
