My 68 B body is an original 383 car.
It came with .88 bars.
Sometime around 35 years ago I took some /6 bars out of another 68 B body in the bone yard.
I haven’t measured them in many many years....... but in my head they were around .840 in diameter.
Edit: Doing some digging on line indicates .840 wasn’t a size for production B body bars...... so I guess that’s not what they are.
