My shortened prop is about 700mm
1974 Fairlady Z s14 gearbox and subaru r180 diffBut what car / year is yours? And what diff are you running?
That's a good idea as I was unsure what to torque it to when swapping mine, would not have to worry about it doing your way.By the way, I am having a new prop made because I wish to use a Subaru diff and retain its flange rather than swap it for the Datsun one.
Hi John. Thanks for sharing the info. How much are Bailey quoting and did you supply them with each end ?Just to add to this. I am having prop made by bailey propshafts and the measurement they require is from face of diff flange to gearbox oil seal face. They use this measurement to get the oil seal to be 20mm short of bottoming out on the slip joint. This allows for the engine/gearbox moving forward and back under braking/acceleration. I think on a factory zed this allowance is around 38mm. I would consider 20mm to be the absolute minimum so would probably move a bit closer to 38mm so maybe 25-28mm. The measurement I will give Bailey is 625mm.

They supply the universal joint attaching to the diff ? That's cool.I am sending them nothing but the details of what I want. They should then have a record of the spec and parts so they can replicate for others (which they don’t currently have). The price quoted is £220 + vat and delivery. I’m ordering 2 off. Delivery is 7 days.
Im doing exactly this on my car. I bought a Subaru prop so I dont have to swap the flanges from the diff...By the way, I am having a new prop made because I wish to use a Subaru diff and retain its flange rather than swap it for the Datsun one.
