A body with B body rear...Sway bar?

I don't do autocross. The only track we have is Not dedicated and is over an hour away.
My car has ONLY a front sway rear bar, 1.03 bars and plain old 3-way adjustable shocks. I have had 245s on the front and still do run 295s on the rear. Rear springs are Stock FormulaS with a full main-leaf added. The car is lowered to about 5.75 under the lowest part of the K, and the sills are very nearly level.
But, my car, on the street, turns in nearly neutral, and exits with oversteer, adjustable with the throttle. If she gets too far off line, I just put a lil toe on the clutch, and she snaps back to line, as the rear tires regain grip. But mostly, the tires are screaming in second gear, with the fronts at near full-lock, lol, cuz that's what I like, lol.
IDK, she's the best handling street-machine I've ever had. But, she's got over 135,000 miles on the chassis now, so, I tend not to push too hard any more. Plus, I'm over 20 years older now as well.

At one time, like two decades ago, I had thought to put a rear bar on, but my Shocks, and near-flat over-load springs, are doing a pretty good job back there. Actually, a Great job, on the streets and parking lots..
