It’s ideal to restore a car with original factory replacement parts. George Yursis of Suamico, Wis., knows this first-hand. He was able to redo his 1970 Oldsmobile Cutlass S W-31 Holiday coupe that way, because he bought the car way back in 1977 when he could still get the parts from an Olds dealer.
Yursis lived in Chicago then. A friend found the W-31 and resold it to Yursis. It was in rough condition, but it was an original W-Machine with special performance goodies and a low production total. While 88,578 Cutlass S Holiday coupes (hardtops) were built, only 1145 of them had the W-31 option.

The W-31 package’s unique 325-hp Rocket 350 V-8 featured a Force-Air Induction System with a special air cleaner and aluminum intake manifold. A Fiberglass Dual-Intake Force-Air hood with external locks replaced the steel Cutlass S “Two-Plateau” hood. The W-31 package further added a heavy-duty clutch; manual front disc brakes; lightweight body insulation; Sports-Styled outside rearview mirror; body-side and hood-top paint stripes; and “W” emblems.
