Early second gen sway bar

[70-SS/RS-L78]

I have a 7/8 rear sway-bar I removed from a Camaro or Firebird a long,long time ago and I am thinking about putting it on my 81 Z28. I parted so many of these cars back when they were cheap I forget what I removed it from. I know the F41 suspensions had 9/16 rear bars and this is definitely a second gen bar. I must have removed it from a Z28 or Trans Am. I feel guilty now when I think about how many Z28's and TA's I parted out. Does anyone know which car these came on or if this was some sort of option. Thanks...

This may help - the brochure for the 1970 Firebird Trans Am states that the car has a 7/8 inch rear bar:

Here's a photo of the rear sway bar on a 70 TA:

Thanks Lee, That's the sway bar. It must have come off of one of the TA's I parted. I have never seen a Z28 with one, they are all 9/16...

Mark, I was about to post the same thing. My 70Z project has a 9/16 rear sway bar.
