There are at least a dozen companies making an Oldsmobile spoiler and most of them are crappy quality. Our Fiberglass W-35 Rear Spoiler is the very best on the market and comes at a very attractive price. This 3 piece design comes with mounting hardware. Do not confuse this item with the $75 plastic junk sold by so many. This item is made of high quality fiberglass made in spun tooling that will last the life of your car.
