R34 N/A Gearbox into R32 setup

[Nic_A31]

I got my hands on a new RB20 gearbox only to find it has a speedo sensor, obviously coming out of a N/A R34.

How can I go about connecting this up to a speedo cable?
I've read through R32 RB25 gearbox upgrade guides, which involves making a hybrid of the R33 and D21/D22 Navara Speedo drives to connec them to the R32 cable.

Does this work for later 20 box?

Either way I have to order something from Nissan
so what's it going to be ?
Nav speedo drive?
or early RB20 speedo cable drive ?

I also bought a 20 box out of a R34 N/A to put into my 32.. pulled out the bung where spedo normaly slots in and my speedo slotted strait in.... pretty sure the speedo should go in without modification...

it will go in, its the tooth direction and tooth count on the cog that is the issue.

Are we talking about a na box from a 34 25de NEO or from a 20de NEO which has no provision for any gear drive at all

Definately a 20 box, I put it side by side with my other box last night, the housings and input shafts are the same size ...where the speedo cable would go, there is like a cylinder coming out of that, and then out of the cylinder is 2 onto a connector.
I'd have guessed R34 N/A or R33 RB20E?

Did you not have to atleast find a speedo drive ?

nah didnt have to find/ modify anything...went in peice of piss, speedodrive had a blanking plate over it so had never been used before, maybe someones done something dodgy to mine previously , but spedo is acurate and smoother than before, we goodluck mate
