where to buy factory sway bar bushings?

For my factory 1965 Barracuda Formula S I adapted aftermarket and they now work fine. As long as the bar is held snug, any adaptation will probably work. See thread below for an explanation. I used 13/16" aftermarket bushings and just cut off the mounting tabs and put the aftermarket bushings inside the factory tabs. Meanwhile, here are the pictures I took.
