I think the Corvair tubes are thinner walled than the Corvette, and probably
correspond to an off the shelf tube and yoke match GM used elsewhere. The
Corvette shafts DO have MUCH larger U joints than the Corvair, and I believe the
yokes, et al, are specific to that vehicle.

Hi Cash,
The physics is what it is all about. The VAST amount of the torque is
transmitted along the outside of any shaft. The center of a solid shaft
transmits
zero torque. This is why driveshafts have been hollow tubes since the early
days of automobiles. You save material, you save weight and there are cost
savings. Someone asked about the size of the half shafts of Corvettes of the
same
era thinking that the Vair half shafts owed their large size to Chevy using
common materials. I would have thought the same thing. I went out to my
garage
and took measurements of both my '66 Corsa and spare half shafts from my '65
Vette and was very surprised to see that the Vair shafts were almost 0.25
Inch
larger diameter than the Vette units. I would have thought either the same
or the Vair would be smaller diameter. Imagine that.
