window slide / ideas 66 fury 2door

so I took apart the passenger rear quarter window assembly apart today as I am getting the car ready for paint and found that one of the slide parts is broken. Anyone have any ideas or parts cars that might have one? I have thought about having a machine shop custom fab one but I'd still need the roller assembly on the one half. The first photo shows the broken portion that holds one of the rollers, the other pic shows what its supposed to look liketempImageooHzGO.png
