Good eye, and part of the reason I took the pic, and why I am sometimes leery of using 70's solutions today.

About 75% complete. The chassis should be a little stiffer than before
I keep wondering how different it will be to drive?

I see your main rollbar diagnol is the now preferred one piece. Since you are 75% finished, this is a leaf spring or a 4 link rear chassis, because your rear down bars are not to the rear?
I also like personally but seldom see it, but a low as possible bar tying both of the bottom legs of the main hoop together, any side impact would without any lower bar would depend solely on the chassis sheet metal floor with a large DS tunnel in the middle, and a bent OEM crossmember, not a lot of protection for the occupants, IMO, and easy to install this additional bar.

Any idea what it's bolted to? If it's the sub-frame connector or something attached to it then things may not be as bad as they look.

Concur on tying the lower ends of the main hoop together. Wouldn't mind seeing all four points on the floor surrounding the driver tied together. One car that I did some detail fab work on had an X between those points as well. The intersection of the X tubes and the tunnel was pure art, but this was way before digital cameras so no pics.


I used to swerve around my hallucinations, now I drive right thru them.

I noticed this too. Perfect arrangement for a coil over conversion, but less than ideal for a leaf spring car that is putting loads in to the rear most part of the sub-frame.

For years I had thought that the roll cage in the `Cuda was built wrong when it came to the rear down tubes. It turns out that my roll cage is built correctly to SCCA specs which is from the main hoop 45° degrees to the wheel wells. I called two SCCA tech inspectors to verify this as well as tubing size specs, etc.

Originally that's how All American Racers built the Trans Am cars were down tubes from the main hoop to rear leaf spring perch. What SCCA rules and engineering requires currently is down tubes from main hoop to go at 45° deg down to the wheel wells. That way in a rear end accident it can crumple the rear of the car without transferring additional force through the down tubes into the main hoop therefore not compromising/kinking the main hoop & halo. I also have a fuel cell cage back there to help absorb any rear impact.

The reason I brought this thread back from the dead is just to clear up some confusion as I will be tig welding in the cage on the 73 Challenger build. Felt dumb for years thinking my cagebuilder installed it incorrectly when he was actually correct haha! I will also add in tubes that tie in the torsion bar crossmember which "mirrors" it inside the passenger compartment as well as a tube the ties both legs of the main hoop together. I'll get video to document and post it up on our YouTube channel next year. Still have to buy all the tube because I'm broke haha!

Not pointing any one person out, just replying to the last post thanks!

I would put a bar from top of door bar, attached to main hoop and down rearward to frame rail in front of or next to wheel tub and add torque box. That way all rear end forces go into structure or at least help to stiffen the fronts mounts

" I also have a fuel cell cage back there to help absorb any rear impact." eek tsk

You put fuel in it?

Sorry, I'd be much more concerned about a fuel fed fire ,then any rear crumple zone advantages.
