Body removal from chassis

WOW looks like you all need to vote out your government and get some people in there that have a clue.

So it is ok for you to buy a car and do a vin swap?

The vin on mopars is on the chassie not the "frame"

So this other car has a standard frame (like a truck) already under it?

Photos would be very helpfull

I dont have photos of the other chassis as I havent purchased it yet, still deciding which way to go.
As for the vin number a new one will be supplied by the transport department

Is it possible to purchase a wrecked modern Challenger in Australia?
One of our club members purchased a rolled-over Challenger here in SoCal, removed the interior, cut the body off and put the complete floorpan/running gear under his 1970 Barracuda. He also adapted the entire interior to the Barracuda. The result was a 50-year old Barracuda body with a complete modern Mopar driveline and interior. Everything works as it should, including the heated exterior rearview mirrors.
It's a beautiful car and most people at car shows don't have a clue what went into building it.
I don't know if your Aussie laws would permit something like this or not.

Good Lord thank you for that! When you said gen 3 my mind was on MoPar. Then someone defined it as an LS. Where that came from only they would know. I've been waiting for you to correct that silly notion. Again thanks.

Or you could go back and read my edit.... lol.. It's all explained.... had a bit of a brain fart.

No worries, but but I did read his and yours twice before I posted. Must've been in the interim:thumbsup:
 
Out of curiosity .. what would prevent you from just making gobbs of HP with a year correct 340 / 360 or even a 383 /440.

Can you add EFI to an older engine?

Thats my full back plan. I already have a the running gear an like the idea of the gen 3 swap. Plus our new rules prevents me legal having more than 270hp in the current chassis.
 
So in a unibody most of the frame members are 3 sided and the fourth side is the floor pan. I don't understand your specific application, but a big motor doesn't usually require ditching the original subframes and replacing with a full frame. Before you pour the big bucks into a rolling frame, I would suggest the you look into US Car Tools frame stiffening kit. This included connectors between the front and rear subframes, torque plates that box in portions of the the existing frame front and back, stiffeners that install up in the front inner fender panels and something that bridges the front frame rail ends over the radiator support. If you need more you could install a roll cage that is attached to the frame system as elaborate as necessary. What I don't get is what you are doing with the car that requires all this. Certainly the gen 3 hemi doesn't require more than the frame stiffening kit.

Registration rules in Australia they are strict with car mods now. The kits from the US will need to be engineered also for my car to pass, this process means the engineer will need to do thickness test of the frame connectors. For example for me to put a tubular front end in my car the engineer will have to literally destroy it to check the thickness of the tubes etc as most of the companies that build them wouldnt supply build data sheets.
Might be easier to move to the USA haha just to have fun.

This kind of repression is why our founding fathers wanted a 2nd amendment. They knew the government would be coming after our wheels.:lol::elmer:
 
To be fair, I've seen Ausi cars "converted" to convertibles, simply by cutting the roof off. Not the best way to do that in any country.

All convertible cars have full chassis aswell not just a roof chop. Definitely not my thing but hey each to their own I guess ‍♂️

The thickness of the metal can be accurately verified with an ultra sound tester. The metal composition can be verified by sampling a few filings then testing with a spectrograph. If your inspector is saying otherwise or that you need a full frame under an A body to allow the use of a higher HP engine I would be questioning the credibility of the inspector. I love going toe to toe with folks who’s decision making clearly show they are in over their head.
I am referring to the inspector that you are working with. Or perhaps you, if you actually believe that you need to section parts to verify metal thickness,,,,

Hi Im after some knowledge of whats the best/easiest way to remove an A body from the chassis. It looks to be a lot of spot welds holding it onto the chassis rails?? The body im removing is of a dodge dart equivalent in Australia.
Just hoping someone on here has done it an can lend some tips before tackle it.
Cheers

SO UPDATE ON MY POST!!!!
Spoke with my local department of transport and a hemi gen 3 swap is not allowed. Not even with a strengthened chassis. So back to plan B, 360 period correct motor with efi.
Australian laws aren't fun
So no body removal/chassis swap required.
Thanks for the replies etc

Another cost saving process that didn't help the strength of the muscle cars. The camaro's were worse when front end was bolted to floor pan, not welded like Mopars. The only cars with a full frame were the Chevelle's.

Impalas, Corvettes, Monte Carlos, Trucks......I can keep going.
 
I don't know if an apology is in order, but I think most of us here in the US had no idea how strict your laws are regarding putting modern engines in an older chassis. But as a few have mentioned how difficult it would be to remove the body from the unibody frame. Good luck in whichever way you decide to go.

Well the regulations and approvals do vary quite a bit state by state here in Australia, in South Australia where I’m located it is possible to get cars approved by the Registration Authority with the assistance of their designated consulting Engineers. They must ensure that the vehicle can pass a torsional strength test and then also pass dynamic swerve and brake tests and that all mods are soundly “engineered”.

Have you checked recently? The vsb14 is being up dated, the guy I spoke with which was the head of western Australian department for mods said all other states are the having the same rules with the hp in pre adr cars. Old rules was cubic inch measure and a power to weight calculation. Till they finish updating the vehicle standards this 180hp per tonne is the rule for pre adr cars. However when i asked how long that will be (as I would wait until its updated just incase it changed for my build) he said they have been at it for 18 months so far an couple be a few more years yet. Also he mentioned the 180hp for pre adr cars will stay Australia wide. Be interesting to see if the other states are the same...

Interesting, sounds like you’re up to date with what’s happening in WA, I still know of local cars being engineered and approved with high HP drivetrains. I’m currently building my car and for all of the reasons that you mention is why I decided to stay with an LA combo. I’ve still got to get it engineered though

If they had approval prior to the changes then its allowed ( well thats in w.a ) do you have pre approval for your mods?
 
What would happen if you bought a car from the US that has been modified, or had a 800 up engine in the stock chassie?

How do they know how much HP your engine makes? How often do they test / check, you could build what you want from a stock looking perspective and swap out the engine to a stock engine for testing etc.

You need to move to a non socialist / progressive country. What's next they take your guns, oh wait they already did that.

I glad I'm in my late 50s, I don't have too many years left to have to deal with this BS here in the US when it comes here.
