I need a right rear taillight lens for my 2004 LS Sport. The parts diagrams say it's different from the base model, but I see ones for sale being differentiated by either upper or lower clear lens. The ones I see for sale on Ebay for base models look the same as mine (upper clear lens). Does anyone know if these will fit? The parts diagrams show 6W4Z-13404-BB for the base model and 4W4Z-13404-BA for the Sport model (discontinued of course).
