This is a copy of my post on nasty Z28, but I thought I would put the word out here.

Hi all, I have a 70Z28, very correct and original. My left rear spiral shock went. I need to get a new pair. I am not finding them in any resto catalogs, can anyone steer my on where to get a correct set to keep my car oe rockin!
I also am going to replace my rear suspension shackles. The bushings are bad but I think I will replace with the full sets that are available, just to avoid any problems.
so I need advice on where to get correct 70 spiral shocks and if you think there is a reason not to replace the whole shackle with a kit.


thanks very much in advance.
