stock front stabilizer bar diameter?

[crew cab sonoma]

just wondering what the diameter of the front stabilizer bar is on the Crews.
i never measured the one on my crew while i had it, but was sure it was
larger than the one on my current Ext. Cab, which has a 28mm bar.
i know there are 33mm bars used on most Blazers, but i dont think
the one on my Crew was that large.

also, does anyone know if any on the sway bars used on these trucks
are hollow or solid?

thanks in advance

Production model crew cabs are 33mm and the bar is solid.

I am not sure about the pre-production crew cabs. They may be the same as the extended cab?

All the bars will be solid as it is a torsion spring.

thanks for the info HenryJ.
i knew it was larger than my Ext. Cab,
i just didnt think it was that much bigger.
some GM's do have hollow swaybars.
some C4 Corvettes definetly had them.
in fact, i traded for a set for my 86 Vette.
they weigh about a third of what the
original Z51 bars weigh.
