Striping
Unlike other H-Body models, Oldsmobile kept their striping options simple and limited.  Only 1 stripe option was available for all model years and it never changed.  It was simply a wide, black stripe (with bright trim) that ran the entire length of the car, essentially 'joining' the bumper rub strips, creating the illusion of a black stripe running around the entire car.  From 1975 through 1978 the stripe was given an RPO Code of Y70, but for some reason this was switched to D90 for '79 and '80.  Production numbers below.
