I read on a thread by the guy building a Woody that is was something like the same as the 1HZ starter motor. Which if it is would be quite lucky as they are very common.
They came on Diesel landcruisers from 1990-2005ish.
Looks hor HZJ75, HZJ80, HZJ105, HZJ78, HZJ79 etc. 75, 78, 79, 80 and 100 series.
