If there is enough room, I would go to a place that sells motor starters
and
buy a reversing controller. That's what this looks like. They come with a
mechanical interlock that physically prevents both contactors being closed
at once. If you don't need thermal overload protection you can buy one
without that. If you can take this in they may be able to advise a
replacement.

How hard could it be to build a replacement with some off the shelf relays
and perhaps a few diodes?
