What 5-speed tranies will bolt to the a-12???

The early small boxes (56 series) are getting a bit thin on the ground these days, The 60 series box from the B310 sunny will do it
There's a 63 series box which is the biggest, we never really got them in NZ.
Dellow engineering also do a bellhousing to put a toyota T50 box behind an A series.

Take a look at the Drive Train Tech Section.

I have a celica 5 speed that will, very strong box.

I have a 60A 5speed you can buy im asking $450 that will bolt straight on.

The Celica/Corolla T50 5-speed is usually taken from an AE86 Corolla and requires a custom bell housing to fit the Datsun motor. More information in the five-speed article referred to above.

The 56 nissan boxes are the old rare ones as in the 1973 B110 GX-5 or from NISMO. The 60 transmissions are from the 75-78 B210, I think.
