I have an 8x10 film holder with cracks on both slides. Is there any way to fix them?

One has a long (2") crack that starts at the edge and goes towards the center. The other cracks are like those little radiating circles you get on your windshield when a rock hits it. There's one on each side. Each are about the size of a pencil eraser.

I'm thinking I'll probably have to find replacement slides but I thought I'd throw it out there first.

Thanks
