Listed from stiffest to softest, front bars came in the following flavors:
34mm solid

34mm hollow
32mm solid
30mm solid

Rear bars, all solid, start with the ultra-rare 25mm bar found only on a few Pontiac Firebirds. Moving from the stiffest to the softest, rear bars were also available in flavors of:
25mm
24mm
23mm
21mm
18mm

In order to differentiate the hollow bars from the solid, look for the small blow holes near the end link seat area on the underside.
