Rear sway bar bushings?
 

Today I am ordering new bushings for my 91 z28. My mechanic told me i need "Rear Sway Bar End Link Bushings". Ive looked all over and cant find a size for them. Ive seen 18mm but im not sure. If anyone knows its appreciated. Thank you

End links are one thing; bushings are another.

End links don't have a diameter, all they have is length. You can buy at AZ or Summit or Jeg's, or from several of the board sponsors, by length. They need to be 2½" to 2¾" long. Not real critical.

Bushings fit around the bar and need to match the bar diameter. They're available from all the same sources. Put a Crescent wrench on the bar right next to the bushing, close it on the bar, slide it off, and measure how far apart the jaws are. That's the size bushings you need.

Don't get stock ones. Get polyurethane.
