I have a 76 Nova with a big block in it . The problem is I think the rear shock's are too short. When I jack the car up and unhook the shock's there is 3 inches between the mount and the shock. The car use to have air shock's. But I want the car to handle.It doesn't sit up that high when I let it down. I was thinking of shock extension's with monroe gas shocks does this sound like it will smooth out my Nova? I also want to install a rear stabilizer bar Appreciate any input.
