727 Question

There's only one long shaft. They are a little longer than a 904, and your shaft is going to depend on what rear axle you've got. As old as these girls are, I'd NEVER take anything for granted. Some cars, like my 67, really should have the axle moved to the rear an inch or a little more, so if somebody DID that, none of the factory length shafts you find are gonna fit, anyhow.

The rest are very short as in some motorhomes, or the adapters that hook up (bolt to) transfer cases in 4x4's and some heavy/ truck units that had the torque multiplier or whatever it was called.
