Well, my synchro in 2nd...

the Z workshop in brisbane has quoted $240 for a single synchromesh :-/

Will a 5 speed from a 240K fit into the Z?

What are my options?

A 240k five speed will fit fine.

So will just about any other Datsun gearbox! I had a 180B box in my 260 for a while, and it was fine. Bolted right in and didn't break.

Another option is to buy the synchro & a workshop manual and fit it yourself. Datsun gearboxes aren't hard to work on.

You can also get a silvia box to fit. Take a look at

There is a page there somewhere about how to do that.

$240 Isn't that bad a price for the work involved (I'm assuming you are talking aussie $$$ and they are doing the removal/replacement of the gearbox), but you shoudl be able to do it yourself for less than $100.

Good luck.

thanks a LOT for that help - now I actually know something about the gearboxes available to me
