Columbia Viva-Tonal 710 Door Repair

[pg1876]

Considering purchasing a Viva-Tonal 710 in overall good condition aside from the main center door, which is detached.

I understand that this door should open down and then slide back into the cabinet - can any 710 owners better describe the hinge/roller system in this unit? I am trying to gauge what it’ll take to repair.

Posted below are shots of the cabinet and either side of the detached door; at least one piece of hardware is missing it seems.

I'm currently trying to repair a Columbia Viva-Tonal 620 with the exact same sliding door problem. The parts of the hinges attached to the door are still there, but whatever goes on there is missing. I would also very much appreciate any insight on what these hinges should look like. Picture shows what is left.

Thanks
Andreas
