why not just get the one made for a cav?
rksport touring with the stock one i think would look kinda the same
just get the bomex wing it looks kinda like the TRD one.
its posible that it might fit but if it's longer, you'll have to cut and re-glass the wing to make it fit....i've thought about doing this to my car but have never pursued it...if you do decide to do this, keep us updated on your progress and good luck!
