Removing Torsion Bars? and leaving them out?

Don't know exactly how a 67 Cuda is, but if you take the torsion bars out of a dart the first time you hit the brakes backing up it'll take the control arm right off the bushing and pin.
The bars are what holds it on.
Thats why you can remove the clips for the bars and pry the control arm back to replace the bars.

I just looked it up (67 cuda arms) and you CAN NOT remove the T bars without a different design lower arm.
Otherwise only the bushing rubber is holding it on the pin, and with poly bushings you wouldn't even have that holding it.
