280z propeller shafts with 4 speed

[ennisdavis]

Which years came  with propeller shafts with replaceable u-joints?

[Zed Head]

None of the 280Z's have replaceable propeller shaft joints.  The last model to have them was the 260Z.  And that was probably only the small bumper 260's.

[ennisdavis]

So will a 260 or 240 driveshaft fit a 280?

[Zed Head]

They will.  But the first year and a half, about, of 240Z's used a shorter shaft.

I found a guy with a 71 240z driveahaft, its 1" shorter. Are the auto vs manuals versions the same?

[Zed Head]

They are.

But that's probably a very early 240Z shaft used on the cars with the forward-set differentials.  Those used a shorter propeller shaft.  People use them with the 71C transmission conversion, but they're too short for a stock 280Z coupe with a 71B transmission.

Edit - actually I think that it would work but you'd lose that inch of engagement with the transmission.  I think it might be closer to 1 1/2" if I recall right.

MSA has replacement shafts. Start fresh and the shafts they sell are stronger and have replacement joints.

[ennisdavis]

Would like to buy used and keep cost down. Spending $20k on a  280z thats would be worth $10k would be foolish.

Do the autos and manuals have different spines on the yolk or different lengths?

There you will find everything you need to know on model year/configuration. Once again please take a look. It’s the Z Bible on part number sourcing.

According to this they are the same. Everything i have seen on forums, the people say different. As far as the length, they all look about 30".
