Need Silvertone Tru-Phonic Tone-Arm (cabinet acoustic )

Greetings,

I'm looking for a replacement tone-arm for my wife's newly aquired Silvertone Tru-Phonic ( acoustic cabinet )

It is damaged at the end that connects to the reproducer also, at the other end, it doesn't have the "play" that allows the reproducer to move up/down.

I've never had to find a replacement part for our phonographs, I'm not having luck finding parts online.

Thank you to anybody who can point me in the right direction.
