Well after going to have a look cause i was lazy before, My mistake, I was thinking of #1 and #2, not b and c.

Dunno what that box is from then.

this looks like the box i have.... can i use it and is it as good as the stumpy?

The main good thing about the stumpy is the length -- same as Datsun 1200.

The 71C is a stronger transmission, but it is the longest one.

so why do people use the bell housing off this and the case of an r30 if u can just use this box?

It's the length -- same as Datsun 1200. So the shifter comes up in the right place (no cutting of the tunnel) and a stock tailshaft can be used.

Bails that box looks like the longer one. If its a 71c you have then put a ca bell on it. There stuff on ozdat about converting the stumps to ca friendly between 71b and 71c.

I picked up a navara d21 71c box. Ends up too much a hassle for me after setting the car up for the stumpy box. So swapping for a dog leg 63a box most likely.

i have 71B... i am assuming that its in between the stumpy and the ca18 box... farkit i will just buy a maddat one and be done with it

Set it up for a long box bailz, stumpys getting hard to find now

Townie the pics show a 71c all C boxes have that sort of shift design
yet they all vary internally with even alloy sandwhich plates on the
pintara ca20 while cast iron on the CA8de and T boxes.
On a light datto either ones are pretty much stronger than abused boxes
from 6 cylinder engines but you can be lucky with a low kms one.
The maddat price is pretty good for a guaranteed box with no hassles but
if you blow it up then you will be in strife finding a replacement while
the long boxes are very common and attainable.

The exact reason I was going to use a full length one, the boxes themselves are cheap and very obtainable, The shifter was going to be set back a fair bit as poer the pics, I just fully got over ca18's tho, Way overdone.
