crushers are definately not fender replacements they just bolt on over...ill show pics if you want.
i love PSC but i will suggest against buying the PSC trail corners unless you find them used. Powdercoating sucks and they didn't line up right, but their Crusher corners fit perfectly and i painted them so they look good.
TnT customs, Blue Torch Fab, are two that i thought of quickly. i know there are more.
PSC makes fender supports that bolt to the roll cage and to the tub. They are meant for use with their rear stinger t/c. but im sure you can get them seperate.
