One of the worst duffle cuts I've seen.
I would definitely try to save the stock but it requires someone with good tools and skills to fix this mess. In addition to being rough cut, both pieces have been split lengthwise by the drywall nails and the staple underneath. The first step should consist of removing nails, wires and staples and then stabilizing the split pieces with Resorcinol, Acraglass or Devcon. Wood glue will not work for this repair. Note to Bubba: No, Gorilla glue or J.B. Weld won't work either.
After stabilizing the split pieces, the cut needs to be cleaned up and a shim made, preferably from red laminate. Dowel holes need to be drilled to hold the separated pieces and the shim together, in conjunction with one of the glues mentioned above. An alignment fixture needs to be fashioned from a straight wood board and the stock pieces aligned and screwed down on it. Final alignment check, then outline stock pieces on alignment fixture and remove front piece. Coat all contact surfaces liberally with glue, including dowels. Screw down in fixture, clamp and secure with clamps and tie downs, remove excess glue and let cure for 24 hours.
Clean up glue lines with a sharp razor blade. Now the stock is usable again but still has 2 ugly grooves where the wires used to be. Right now I don't know how to make them less unsightly, it's going to be a challenge.
