ive got a few major defects and you dont have to take it to vic roads, u can take it to any roadworthy tester and get a RWc for it and just present the RWC to vic roads, if they persist on seeing the car even if you show them the certificate (which has not happend to me) just say its at the mehanics becuase i aint allowed to drive it due to the defect and all should be fine, i wouldnt worry bout the steering wheel to much just fix the BOV and the height of your car and you should pass. and id advise you to go to a local roadworthy tester because they are useually more leaneant the vic roads
Cheers
