71 442 W30 - Two Plate Clutch? Interesting...

[csx289]

I just bought a 71 442 W30, incredibly original 20k mile car, from the second owner. It is an M-22 4 speed car, and on the original window sticker an option listed is "Clutch, Heavy Duty Two Plate" .

The car has the original clutch and has never been apart, so I am wondering what to expect? They made 247 W30 4 speeds in 71, has anybody seen this option on one before, or any other Oldsmobiles for that matter? I can't recall Pontiac offering a dual disc clutch, but I could have missed that as well.

I know Chevy had a similar option (code KE?) ,and had seen the option listed in Olds books but never on a car.

Anybody have any history or coments on it? Curious to hear from the Olds guys!

Thanks,
Colin
