Short of the icelandic version, I'm not sure you have many/any options for flares for wider openings (besides the bushwacker cut-outs). Of the icelandic versions I've seen, it's always been FZJ-80 or FJ-80 land cruisers. Bushwacker only makes the extend-a-fender flares (standard flares) and cutouts for the 1984-1989 4Runner body style. Warn used to make a standard flare almost identicle to the extend-a-fender flares, but I don't know if Warn still makes them (I own a set). Regardless, the Warn flares are for a standard wheel well. Toyotafiberglass.com makes fiberglass sides with a flare built right in it. There's a recent thread on here showing pics, though I'm sure you've already seen it. If you or your bodyman are crafty at making molds, you could try making your own custom flares out of fiberglass (or metal if you'd rather weld).
