Fender mod.

Yea, probably no mud there unless you travel in and down a river. lol.
I opted to not attach my support, It seems fine; nice and tight.
Looking at 4 different youtube vids on fender mods everybody has a gap. Even one Irish guy who said he didn't want to, has a gap.

I cut my liner wider. Then sliced it to accommodate a rebend with a heat gun. I bent it around the fender body. I screwed in a large stir stick just to flatten the plastic better while I work on the driver's side. The next day I removed it and used a plastic Jeep Rivits rather than zip ties like every youtube person I watched does. I could have done a better job closing the gap at the top, but.. hindsight and all. I did have to use one bolt and fender washer to hold things tight enough for me to like. And of course, with the liner in place I can't get to the backside to remove it so... it's a permanent fixture. lol
Not perfect; but not bad for this first-time non-handy guy. I'm surprised that the "experienced" youtube people don't do it this way. The drivers' side is being more of a bitch. It's like two separate custom jobs, exactly like.
