There was a long thread about bushings in general some time back and it focused on Chevy stuff from Ground Up Resto www.ss396.com.
These people just replaced all the body mounts on my 71 Skylark, they may sell what you need. Energy Suspension energysuspension.XD.com Phone 949-361-3935 Talk to Billy Ray Harrill, Product Development Dean
I bought some for my 67 Special from SS396. I needed 14 mounts wich is the conv. kit. All 14 mounts were the same size and they were supposed to be with hardware but did not include washers. Only the bolts. There was originally 4 different sizes height and o.d. wise. I made up difference for the taller mounts with washers. There was 2 holes in the frame around the seat area I needed to make bigger for the 'same size mounts'. Also if you get the rad cradle mounts they are shorter and smaller width wise than orig. that can affect fender alignment. There was a previous thread on a different place that sold various size mounts individuallyhttp://www.restorationspecialties.com/. I've never delt with them but having the proper mounts will make things that much easier. Ray
