Thanks Jon. The reason I ask is that I removed a rear bar from a firebird years ago in a junkyard. If I remember it was a blue 68 HO350 car. I remember it had the stripe down the side. The thing is, the upper mounting brackets were attached with a small u-type bolt that extended the two threaded ends out thru the frame rails. I removed the bar, etc. and then removed the back seat to get the two u-bolts out. They were under the floor boards and apparently installed thru the frame rails prior to the floor boards being welded to the rails. I had a chisel so I made some ugly holes in the floors and pulled out the u-bolts. I ended up installing the bar on my 60 Camaro which I sold a few years later. I used a hole saw and used bolts to re-install the bar. I always wonder about that darn sway bar..and that car also. I may be crazy, but I'm convinced that was a factory installed sway bar. Or I wish I knew where my old 69 Camaro was so I could go check out that bar...probably still on there
Thanks again for theis great T/A racing info.
