I like the look of the fenders in the link for the Exo-top. I don't know who made them.
Bushwhacker offers a "pocket-style" like the one in the link. It only has one fastener where the pic shows two. They also offer a flat style. I know the flat style does not require drilling into the body of your Jeep but I don't know about the pocket-style. For the amount of installation work, and the price, I'd just buy a Dremel and go to town on the OEM fenders.
Either way, plastic fenders can get ripped off on the trail.
IMO, for the amount of work involved, and few tools required, bolt-on steel or aluminum fenders are well worth the money when considering, at least, the laborious installation process for plastic aftermarket fenders. There's still drillin' to do with plastic fenders, but it's into the OEM inner fender component...and a bunch of fiddly clips, etc. to play with when puttin' it together after all your prep work.
All the work doesn't seem much different to me than doin' metal fenders, tho' I'm sure there's a whole lot more due diligence involved before and while one drills into their Jeep.
Save your money, Dremel (or other) your OEM fenders with finesse, rip them off on the trail, then decide what to do.
I checked the capacity for a 2dr Exo-Top, 300lbs. Still respectable...and I'm likin' it more and more.
