TOPIC: SUN 'N FUN Seat Back Support for '63 Niagara

I have a '63 Niagara I just picked up in June (my first boat) that needs two SUN 'N FUN seat back support brackets.

If anyone has some or knows where to find these, I would appreciate it very much.

The boat is in excellent shape and very original. It is just missing two of the brackets. The photo below shows what I am looking for. Also, here is a picture of the boat in tow behind my '63 Studebaker Champ pickup.

Thanks,
Matt
