Sway Bar Question?

Just a heads up, there were 76 factory valiant cop cars with rear bars under them. I have one in my 69 with 340 suspension and the front bar, works great, car is flat now and tends to over steer if pushed hard.
You might as well say no a bodies ever got a rear bar as rare as they are now and of course no early ones came with it.
The frame mounts seem wider then the b body ones but other then that are similar, and the shock plates are the same I think.
