I have an 80 Camaro that did not come with a factory rear sway bar. My frame has 2 holes on each side of the frame that look like the right location for a sway bar bracket. Can someone tell me what size bolts to use on those frame holes? It is hard to tell if those holes are threaded but I hope they are. I assume I can use them to install an aftermarket sway bar. Also, what sway bar diameter was factory? Thanks for the help. Kevin

 

I have a 1979 Z-28 and on mine they were threaded .with rivnuts .I believe they were 3/8s fine thread with a 5/8 rear sway bar .But depending on the sway bar set you are going to use .And what you are going to do with the car .Using factory (Z-28,F41) and aftermarket types can be different .and or no rear bar at all.

 

Thanks for the reply.
My holes are there and I cut 3/8 threads into the frame. I looked on Summit and they have a 1 inch bar that should fit. I can't wait to install it.
