Rokblokz fit tacoma WITHOUT flares?

I see the Rokblokz have slotted mounts. Would they slide inward enough for a Tacoma without flares (I have an SR)? If not, it looks like the material is flat with no embossed border so could they be trimmed on the sides to fit the no flare Tacoma? I need low profile flaps to fit my 265/70r17 tires and I don't want to mess with drilling or cutting universal flaps. This eliminates the Plasticolor and Rally Armor universal flaps. Are there any other low profile (aka flat) pre-drilled flaps for no flare Tacomas?

 

They use the holes from the flares, so I would imagine they would still work. If you're strictly talking about aesthetics and not hanging forever off the side of your truck, I'd say get the regulars and the slots should give you enough play to get them flush or where you want. But, if you're trying to slide them inward doesn't that defeat the purpose of them? Outer tire edge will fling crap past it and you've wasted $150. What's your end goal?

 

I'd like them flush or maybe slightly outward. Since I don't have flares, they would need to be inward more than a truck with flares and I'm wondering how much adjustment they have to do this.
