I have my rear end pulled out to replace the gas tank. While I'm at it, I figured I would clean everything up. I need a set of sway bar bushings, Prothane sells universal sets, I just need to know which one as I forgot to measure and the old bushings are at my shop.

The car is an 83 Z28 with the G80 rear end RPO. Here's a link to the bushings:

Your best bet is to measure the sway bar itself.

As I said the car along with everything is at my shop or else I would. I was hoping to get them ordered tonight.

 

If you car's rear is OE, then you should have an F41 suspension and a 21 mm rear bar. Check the following link:

Energy Suspension or Prothane are your best bets, do u plan on gettin polyurethane or rubber? I'm not putting my word on it but i think the Z's came with 19 or 20mm rear sway bars.

 

Thanks! I still don't know which style I need though, and at this point I might as well wait until tomorrow.
