i dont know if there legal on a road car but i dont think they are. if you go to and racing gear shop you can get ADR approved ones and they might be ok. as far as bolting them theyl need to be engineered at least to pass. the bottom bolts can go in your existing mounts but the top ones can only be between certain angles. these are things ive delt with for rally cars not road cars btw. i think your best bet would be to ring your transport company and enquire the legalitiys of it. hope that helps a bit mate.

Does anyone have harness seat belts in the ute if so how did you get them legalised and we're did they bolt to?
