Could they be from here? http://toyotafiberglass.com/4Runner.htm
Might spark your memory.
That's a definite possibility! Only other thing I can remember about the fiberglass stuff is they used to make an Ivan style fender with the hood too. Only place I can find that is Hannemann Fiberglass, but really I dont remember. I think what I probably did is ask the sales guy at the off-road shop I worked at to just get me some fenders and then they showed up.
