Aftermarket rear mudflaps 3rd gen tundra are crooked

I wanted a different set of mudflaps than the OEM style so I put these TRD style ones by Tuffskinz they’re simple to just bolt on using the existing threaded holes, but you do need longer bolts and they are included. The only thing is they seem to bend inwards making them look kind of like offset or crooked and it looks kind of crooked, and they are not completely straight because the plastic on the wheel well kind of bends in Kind of toward the front of the truck instead of going straight down and being completely straight. has anyone else Experienced this? does anyone have a simple, quick fix or idea?
It may be kind of hard to tell from the photo, but it’s definitely crooked. They look more like wings than mudflaps.

 

Same with the ones I got from Amazon. Bothered me for a minute, but I got over it. They still work.
