SD22 engine mounts = SD25 mounts??

SD diesels were widely available in the US in the 1981-86 Datsun/Nissan 720 pickups, and in Canada through '87 in the D21 pickup.

im just curious will an SD22 bolt up into a truck with an SD25 stock? and do the tranny's bolt up?

from my experience i understand that the blocks are pretty much alike.

I would expect: yes, and yes. Perhaps someone with direct experience will chime in.

The SD25 block has five mains rather than three, and a real rear main seal.
