Torsion bar diameter for 440 swap

My 1.03 bars have never given me the impression that they were too big,(or have they,see below).
My SBM 68Barracuda scaled at;............. 1750/1717r=3467 total,
with me in it, in track trim, with 200pounds removed.
Here's what I took out;
Exhaust; 3"TTI/Dynomaxers(72), rear seat(64), heater(16),.....total 152pounds
front bumper(30), sway bar and skidplate(18),.........................total 48pounds
As you can see only the 48# came directly off the front, the rest is between the wheels, with about 100 of it right in front of the rear wheels.
If I had to guess, in street trim;...............1850/1817r=3667
but the rear seat never went back in, so... 1850/1753r=3603...That was 2004, and since then I
have gained 25 pounds, so guessing now; 1868/1760r=3628

But; I gotta tell ya that at my slightly lowered rideheight, there is very very little preload on those PST bars. So little, that sometimes I am cornering on the poly bumpstops. And when I hit certain speedbumps in my town,, POW! the bumpstops jackhammer the front straight up.So in that light, I think I could run LESS bar, and more rideheight, and let the shocks handle it.
but no way am I gonna do that,lol. I just slow down for those, or lower the tire pressure on Friday afternoon, cuz, you know, I love to smash those speed bumps when passing the tuner boys crabbing over them while holding up traffic to do it. BadaBOOM! Ya ok, so that might be dickish, and I know it, so whenever I do it, I lay on the gaspedal too; why be a half-dick, when you can be all-dick. I my defense, they all know me.
