The body going on is a single cab body from an 82 or 84 hilux (cant remember

Once it goes on my plans for the body are fairly simple- FG guards from steve in hamilton with the larger arch (same as jafa's) and replacement doors without dents or ripples.
Q1, whats the model code/name for my cab. I've been getting confused.
Q2, What other trucks/years have compatible doors etc. The cab currently has doors that dont fit too well- they stick out past the front guards at the top. I've been told this is because they are from the wrong year truck? What year is this so I can stay away from it.
Q3, has anyone in hamilton got a chrome front grille for sale

Q4, is there a crowd in NZ making tube bars for hiluxes off the shelf? I ask because ive seen tons of luxes on ORE with sweeet armor.
Cant wait to get this shit on there.
