Yes I know its not a datsun clearly, but with the love we have for old datsun, the same can be said for others.
I'm a toyota man myself yet love datsuns also and building my 1200 sedan as we speak.
74's came with the big bumpers here in the U.S but everywhere else did now and here the 73 and older had small metal bumpers.
Heavier then a 1200? Yes indeed, bigger? Yes, but it also has a bigger motor with likes of the 2tc and 2tg motors they were pretty strout new.
