Qld Transport will be able to give you a list of "Approved Persons", but what you have to get approved can change who you need to talk to.
I've used two different guys - both top blokes:
- Steve Blackburn in Annerley who runs his own auto engineering business - he blue-plated my rear disc brakes
- Keith at KCF Rallysport up in Kippa-Ring fabbed up and blue-plated my cage, seat mounts & harnesses (ie he does road-legal race prep rather than engineering people's DIY mods)
Both of 'em are in the whitepages.
