It makes it much easier if you remove them, yes.So I need to remove inner fender to access the plastic nuts on the back?
I just removed mine last week from my 98 Wrangler and it was not fun at all. I felt like I had gone into battle and the Jeep won (see attached picture)!I fought for hours to get my flares off. When I reinstalled, I used SS metric bolts and fender washers. Most of my nutserts were usable, but I didn't trust them. I had another occasion to remove my fender flares and it went much quicker.
I used rivets, actually worked quite well and looked clean. I had to drill the nutserts out anyways so the rivets would be easier to drill out than nutserts in the future. Note: I only did this to the nutserts on the rear that you have no access to. The front I replaced with nutserts, just use antiseize on the screw threads and you shouldn't ever have the issue again.I just removed mine last week from my 98 Wrangler and it was not fun at all.

I have all 4 off and am getting ready to install some different flares (still OEM). ALL of the nutserts spun at removal and 3 of them even pulled completely out. My question is, what did you replace them with and is there a way to keep the plastic "nuts" from spinning on the rest of the fasteners?
I am about to the point of pop rivets and grind them off if I need to replace in the future.
What size are threads on the nutserts on the small flares on the side? (There are a few that are screwed into metal nutserts (I believe they are some of the screws located lower on the flares), I used a needle-nosed vice grips to keep them from spinning. A couple of them on the rear are completely enclosed by the body. Hopefully they don't spin for you but if they do, you'll have to drill them out.
