Simple 1LE sway bar question

Is the 1LE swaybar hallow or solid and How much lighter is it than the stock swaybar on an LT1?

The font 1LE is hollow, 32mm, and weighs 13lbs if my notes are correct. Since it's larger than the stock hollow bar, I suspect it's a touch heavier than stock, but not much. I don't happen to have the weight of the stock bar.

The rear, I have less info on. The stock bar is 19mm hollow. In 1993, the 1LE was 21mm, solid, and weighed 10lbs. Later model 1LE's had a 19mm hollow bar, I don't know the weight.
