Depending on how much they want for the parts Sam is what makes that a good or bad decision.
Yes you will need those parts for the compliance and sometimes its better to just get them than wait around for them to turn up cheaper.
There are a few little things you have to do, so the car meets complaince for TAS rego under the old 15 year rule.
you DONT need side intrusion bars (so dont listen to anyone that say's you do)
and the high mount stop light does not matter here either (if you got it in the wing then it does have to be operational though)
COMPLAINCE NEEDS:
seat belts and child restraints changed (although you can get the original's certified, but its not really worthe it)
drivers side mirror has to be changed
VIN number has to be stamped under the bonnet (and obviously the import papers have to match as well)
Unleaded fuel only sticker on the inside of the petrol flap and depending on where you go you may need the fuel filler restrictor???? (i didn't though)
all lights have to be operational (stop/brake, indicators and headlights)
all windows (electric or mechanical) have to be operational
no part of the exhaust can be going to atmosphere
aftermarket air intake is ok (but again depends on where you go)
number plate lights need to operational
tyres need to meet approval (ok tread left, no cracks/splits in side walls)
battery fasterner
and thats about it really.
if you need a hand with anything then give me a yell.
also i know a few people that can help out with getting the car road legal with your inspection if you like
