Pioneer Spring board

I have a 30 plus year old Pioneer Spring Board. I have replaced the board since they do still make them, but my problem is the spring finally broke. This board is the style with only 1 spring and not 2 that I have seen. I've checked with Pioneer and of course they quit making that type of spring. If anyone knows who I could contact or know of someone who might have the old style of spring, please let me know.
Thanks Britt

Not a clue.

There are companies that make custom springs. If you can give them both pieces of the spring, they can probably come close to duplicating it.
