Lund sx125 flare install

A little disappointed in how these fit. Install was pretty easy and straight forward.
Had to remove weathertec mudflaps and on rear bottom of fender area this other plastic piece had to be removed. Right front was a tad harder than left to install. Left front has a gap between fender and rubber gasket.
Rear fits perfect.
Any thoughts ideas,did i miss something? Any one install these? If so what are your thoughts?
is there a maker of mud flaps that will work with these flares?

 

Did you use 3m tape like the oem flares use? Needed to hold the flare to fender at the gaps you are showing.

 

No i did not use 3m tape,never heard of it didnt say to use nor did the tape come with it.
I will purchase some and reinstall.
Thanks.
