The upper body structure or roof of a passenger car contributes significantly to the total strength of the body of a unit construction vehicle and its removal can seriously affect structural integrity of the original design of the vehicle.

There is no specific regulations under the Road Traffic Act which makes it an offence to remove the roof or upper body structure of a motor vehicle.

However, in the case of passenger cars and passenger car derivatives manufactured on or after 1st January 1969 the removal of a vehicles roof may interfere with the ADR 5A, 5B or 5/100, relating to the upper seat belt anchorages.

Consequently, passenger cars and derivatives manufactured on or after 1st January 1969 will only be acceptable to the Department of Transport if an engineering report prepared by a Chartered Professional Engineer is suppied.

The report must demonstrate that the modified vehicle continues to comply with all applicable ADRs, and that the vehicle meets with the Department of Transport Torsional Rigidity and Beaming Stiffness Test Procedures as outlined in the Engineering Instruction Number 8.

In the case of passenger cars and derivatives maufactured prior to 1st January 1969 no approval or inspection of the modified vehicle is required, however, it is recommended that the services of a Chartered Professional Engineer is engaged to ensure that the integrity of the vehicle has not been degraded.

Well I asked a person today

They said: When it gets to Regency, it will get Defected for the roof chop no matter what. And it will cost just under a thousand dollars to get it cleared.

I am 110% sure that according to Australian Design Rules, in South Australia, any pre '69 manufactured vehicle can have a convertable/roadster conversion without requiring an engineer's certificate (ie: you can do it yourself if you are good enough) but im wondering how or if the Police would like this if they pulled such a car over? If the roadster gets Defected because some cop decided that it should have a certificate, would i get any trouble at Regency? Is it possible that Regency could decide that they would infact require an Engineer's certificate for my pre '69 mini even though the ADR's say it is not required? Or would they say "No, the car was manufactured before 1969 which means it is exempt from the certificate rule, regardless of what any police officer says or believes" I am having a few thoughts at the moment and am just weighing up the good and bad points of my multiple projects. I dont think i want all of them.

Yeah, you are right..... I got a copy of the "modification to motor vehicles" section of the ADR's about 10 years ago.....and they way I read them is: pre '69 you can do what you want......roof chop, supercharger, go for your life hence why my project car is a '62 model

You are right and wrong, because pre 69 cars are before ADRs were introduced but doing conversions like choping the roof off is coveredd by the VSO (vehicle standards) that each state chooses to adopt from the DOTAR documents, so the car will require to be engineered to be legal and registered. The VSO documents tell you what can be done without needing engineering and for body mods its things like fitting spoilers and flares and light mods but if it structural the car will need engineering.

What he said^^ But I note there is a difference between States. example - It appears SA allows a "clean" convertable - no roll bars while Qld insistes on a full and padded roll cage - sort of defeats the purpose of a convertable

Yes, a 'clean' convertible is fine here, but still needs to be engineered, go speak to Steve O'Malley about what he had to do. Regency failed me for having a rollcage and a rear seat, even though the car (1964) is pre-ADR. it doesn't matter. It's a modification so it comes under a different set of state governed rules from what I figured out, from being down there in November, of last year. Basically, they don't like to pass anything modified but they can't not register it if it complies. Do your research! But no doubt they'll make you change a few minor things as that's what they do. For me it was bonnet hinges to be put back on (no bonnet pins) and new brake hoses all round.

Ok, so I'll quote from this piece of paper in front of me...... Information bulletin from Vehicle Operations Section, Department of Transport, Regency Park, SA MODIFICATIONS TO PASSENGER CARS, CAR TYPE UTILITIES AND PANEL VANS No.3e August 1995: page 16 of 24: Convertibles.

read the last paragraph, it says we suggest you get an engineer to check for structural integretity and without that they do not have to register your vehicle and if it is not done all your insurances are invalid including your CTP, you have a peice of paper that is worded badly and is not worth the paper it is written on in a court of law Jon

don't let it turn you off doing a chop but chat with one of the state qualified engineers before you do it and listen to what they say, it is sometimes not so bad after you have a chat and they tell you what is needed, chat to bickworx about what they had to do for the one they have got, nothing is impossible (can be expensive) but like all these things its good to get the right info going in, I have to do it for the imports and the ICV clubmans and once you find a engineer its all good Jon

Sorry Supercharged 850 but the others are right, you'll need an engineers report, Regency don't care about any rules or laws. Get this, I failed (amonst many other things) for not ahve demisters as the inspector claimed it was an ADR, my car is 1964, pre-adr, I said that he said it doesn't matter, you can fight it but the inspector is the one who has the say, and if he says it does matter then unfortunately it does. BTW don't expect to pass first go, with all the correct engineering stuff they wil lfail you for something silly, very silly, like 'evidence' of brake fuild near brake hose therefore illegal. (yes that was one of my fails too, the fluid had dripped down from the bleed nipple alst time I bled the brakes and didn't bother to clean it.... learnt my lesson!) Call Steve O'Malley, he'll know all! He said that the identity checkers who are policemen tried to defect him, I don't know about them, I haven't got that far yet, and all I did was put a 1275 in and no longer wanted an 850 engine no. on the rego.... DOn't be deterred though, it would be more than worth it!

Well in my eyes, it says recommended, but not required. It wont hurt (except maybe in the wallet) to talk to an engineer..... IMO though, if regency told me that my car had to conform to an ADR that it's too old for, i'd tell them to get Edited for Language <Mod edit> Probly wouldnt do me much good, but it's the principle of the thing. Rules are rules. Do we have a lawyer on board here?

Also the ADR for demistors in cars, no longer exists, it ceased in 2001, I think, I read throught them all. But can't be bothered to go to the webpage and quote it. Basically in my case I jsut said, "oh ok I'll fix that." And I'll pass in a few weeks when I go back. But my case is different, covertible is a big mod. As far as I'm concerned it's legal, put it this way, is there a law that says all pre-69 cars must have doors? No there isn't, so take em off! Unfortunately Regency are wankers. No offence to any regency blokes on Ausmini, as one of the inspectors for my car races a Cooper S.
