I dont know if its just me but i never knew there was a datsun 1600 look-a-like in the form of a ute.its known as the Datsun 521 pickup and theres an earlier model representing the bluebird desgin, known as the datsun 520 pickup. I came accross two examples of them out at richmond in a padock, the 521 has 6 stud drums on the front sounds fun Shocked the owner has them for sale, said make an offer, if not they'll continue to rot.
heres some pics, not the best of photo's but you can work them out.
