have the same problem,soooo, i went to home depot and they cut the 1/2" plywood to my measurements loaded it in the car and away i went. DH had to get involved so i marked where i wanted three holes drilled, one in the center of the pointy end of the old ironing board and 2 at the other end. put screws through the wood, covered the board and laid it on the old ironong board and bolted it down. it doesn't wobble still folds up and is easy to move. you can do it too.
