Sway/Stabilizer bar diameter

Is the diameter of the sway bar and stabilizer bar on my 87 Camaro stamped somewhere on the bars? I'm wanting to order new bushings but don't know what diameter to order.

Thank you in advance,

No, there's probably a stamp here or there, but the only mark that tells what they are was a paper tag from the factory. If the car has been driven much since new, the tag is probably long gone.

Option 1 ) Grab a big adjustable wrench, slip the open end over the bar and tighten the wrench as far as you can, then measure the distance between the jaws of the wrench.

Option 2 ) Use a caliper.

It'll be metric, for what it's worth.

Measure it with a pair of calipers.
If you don't have any, buy a $10 set at Harbor freight.
The cheap ones are VERY useful when working on cars.
Also consider buying bushings that have grease-able fittings on them.
Some do not have fittings, and Poly stuff will squeak of it's not lubed up.
(Yes I know HF stuff is probably +-0.002 tolerance)
