Jim,
All '32 running boards are the same except for a few large truck exceptions. I suspect that both Bob Drake and Vintique offer their own versions of the covers. I've used Bob's with excellent results. They are glued on with readily available rubber cement. They come with excellent instructions, but the secret is to attach only a portion at a time starting at the outer edge. You can use pieces of an old inner tube for the portion of the board that attaches underneath the chassis frame. Buy a tube of liquid black rubber at your local hardware store to fill the little holes on the bottom of the boards to duplicate the original nibs resulting from vulcanization.
Don't attempt to install the covers if you are in a hurry at that particular time as patience and persistence are required for a good result.
