Registration inspection looming

I received my registration renewal notice via email recently for the Landcruiser.  Don't know how much it is because I can't open it!  And yes, I elected to have renewals sent to me via email not post.  Whatever the cost, I know it's due for a roadworthy inspection, so once again it's time to check everything over.

• Brakes have been replaced, so no worries there.
• All light bulbs working for once (though a couple will inevitably pack up just as the inspector looks at them as usual!).
• No oil leaks, as all previous leaks have been repaired and no new ones have appeared.
• All new steering joints, so steering is tight.
• New universal joints on the driveshafts.
• All suspension bushes replaced.
• New coolant hoses and fan belts.
• Headlights aimed properly.
• Seats and seatbelts in good condition.
• No rust in the bodywork.  Now what that has to do with road-worthiness is anybody's guess, but I know from bitter experience that some inspectors think it does.  I used to have a Falcon wagon which I kept in top mechanical condition, but it had a small rust spot over the rear wheel arch.  I was informed that I could not re-register the vehicle without having the spot repaired by cutting and welding, and would need re-inspection before painting.  Since this would cost more than the vehicle was worth, I didn't bother.  The infuriating thing is that the spot was there the previous year, exactly the same (and I mean exactly, as I had treated it with rust preventer) and there was no hint of a problem.  I wasted $240 putting in a new windscreen before inspection, and ended up having to scrap the vehicle.  My question is if nonstructural rust is such a major issue, why was it passed the previous year, and why do they pass rusted vehicles in much much worse shape owned by people with darker complexion than me?  I'll leave you to decide your own answer to that.
• Wipers work, horn works, windscreen washer works, all indicators and other lights work.
• Handbrake - well there we may have a problem.  I have completely replaced the handbrake system with new components, and it is still absolutely woeful.  It is the one thing I don't like about the 80 series Landcruiser.  Even brand new, the handbrake just barely passes the NT road-worthiness inspection.  My only hope is to adjust it right up till it has almost seized, have the inspection done, then back it off before driving home.  There's no point taking it to a brake specialist, as it is already new and still doesn't work.  They will simply adjust it up until it almost seizes, and charge me $500 for 5 minutes work with a screwdriver.

Anyway, I guess I'm just about ready for the inspection, so like all drivers of older vehicles, I'll go in with my fingers crossed and hope the inspector is not having a bad day.
