Sorry for how dirty it is.. literally just rained on the way home. lol And also the wrong ordering of images. Images 1,4 and 5 are of the back... 2 and 3 are of the front.
So as you can see for my case...
For the front flaps.. there is a relatively large gap on the top.. I have no idea why other than the peice is slightly warped. The screw is not crossed... it's as far in as it can go on the top and bottom screw (used impact driver until it "impacted" about 3-4 quarter turns. There is also a rather large gap on the bottom of the fronts between the flaps and the bottom side/door trim.
For the rear flaps... it fits perfectly at the top.. I pushed it in as snug as I could prior/during screwing it in... also pushed as snug as possible prior/during installing the bottom... there is a slight gap towards the bottom between mudflap and paint (see above)
Wanting to see if I can fill this (as I have re-fitted and snugged and am positive this is as snug as they will get as they are. At this point, I'm thinking I can either slightly heat them up in hopes of warping the pieces I need to adjust.. or filling the gaps with something. I do like the way they look... so ideally I would like to keep them on. They're on right now anyway because I don't think it's too terribly noticeable..
