was talking to a stall holder at goulburn swap meet who had a couple of datsun bits turns out he has a sedan and a disc brake setup which i am buying soon aparently its of a nissan van (im pretty sure its called a nomad?) from 86 or 87 and bolts up almost perfectly other then you have to make up a sleeve for one little bit. so when i get it home ill try it out and take pictures of the few bit that were modded
[edit] they are also ventilated and have decent calipers from what he explaned
