Delica Truck tranny question.

[Macleod]

My 95 JB500 camper, 4D56T, 5 speed, hi/lo transfer, has parts that are L300 similar, and parts that are not compatible.
The question came up, is the Truck tranny the same as the van?
The truck (or camper) (P25T) is bigger & slower. Not sure what it's load capacity is.

The part numbers do not cross... and some things look different in the diagrams. It seems obvious that the mounting would be different at least (frame vs unibody).
