Hi here I have a d21 stumpy style gearbox I think but not sure what it it
Here are some pics of the bell housing and gearbox numbers but unsure what it suits?
This is the bell housing numbers


Here is what the bell housing looks like


And here is the rear of the gearbox numbers

LZ means it fits either L or Z series motors, also will fit a ka series motor and can be modified to fit ca.

Question for you. Is that lz71b crap stamed before the sandwich plate?, because I thought what is written on the rear conflicts with the front, the rear says 71C which means the better gearset. I might be wrong with that tho, as I am no expert.

Yeah that's what I've been reading, sounds like a ca rear gearset with the l/z front, was thinking it was more like a r30 stumpy but seems not so ill be putting it up for sale would be a good strong box for an l series as its only a tad longer but strong as hell!

Is it a full length box? is that your reason for sale?

The 71C gearset is stronger. The shifter presents like a full length box, in which case your gear stick would be a bit further back.

Yeah can move my shifter back at all so I'm running a 71b stumpy

That's a 910 Bluebird transmission, australia assembled. NMCA is Nissan Motor Cars Australia.

Thats the front bell dd, its 2 trans made into 1

The rear says 5W71C. Which might be same gearset as 71B (many, many ratios were made).

71C is stronger than the 71B and came out in mid 1980s i think.

If you could show us a side on shot of the whole gearbox, it'd help. The stumpy box also has the speedo output on the left hand side of the box, or at least the one I've got has, while the longer B/Bird boxes have them out the right hand side.

Here's the side pics


Speedo drive is on passengers side of box
