With a quick measure in the shed I would say 921 = front of water pump pulley to end of Isuzu bell housing.
If I measure from the front of water pump pulley to fly wheel housing (where bell housing bolts up), it is 700mm. The fixed fan at the front is 60mm extra.
Landy bell housing is too hard to measure from engine bay and it's too cold to be lying on concrete tonight. ;) Plus surely the length of the Landy 4bd1 bell housing is around here somewhere....
Note I could be out by a few mm as well... It was a tape measure eye ball job. :)
