Asking a couple questions-will my A body corner?

Re the original question of can an A-body handle? I recall a Car Talk episode long ago where they reported that a 68 Dart won a road course race for factory cars. I think that was against all manner of "sports cars", but maybe just U.S. models. Still, pretty good for what the public considers a "grocery getter". A bit hard to imagine without independent rear suspension and such, but then I understand that Porsche 911's also have a torsion bar front end.
