theres a full set of skirts on ebay at the mo for £295, they aren't genuine TRD, but he said they were from a mold taken from original TRD's, I don't know ho wmuch TRD's are un painted tho...
edit: the seller (east west customs - how original?) states TRD Body kit, but he did message me when questioned about this to confirm what i've stated above, poor feedback too actually
