1974 Dodge Dart Diesel

this is awesome . I understand a sd33 is a Nissan 3.3l Marine engine that comes n.a. and turbo . Is this correct ? More info , please . I would like to see the coupler for the torqueflite . Where can I get one ?
International Harverster used the sd33 coupled to a 727 in Scouts in 1980 (don't quote me on the year). Rusted, beat up diesel Scouts can be found fairly cheap. I'm sure a decent transmission guy could swap the tailshaft and related internals to go 2wd..
