My bad, I was thinking the Suzuki starter was on the trans bell housing,
the starter is in fact on the engine side. I change my statement, I think
you should be using the Isuzu starter so it matches the block and is the
right depth to reach the ring gear.
But I have to admit, I don't recall ever seeing an Isuzu Starter so I don't
know how it compares to a Suzuki one
