You might be able to save the barrel, by welding up the bolt face remachining to fit, and then lenthening the firing pin, and extractor. After you get it to fit, send it off to re heattreat.
You can tig weld up the gas port, or thread it, plug it and sweat it. Set the barrel back as usual and then redrill a new gas port.
The second method is probly less risky, both require you to be a handy machinist. Unless there is somthing really different on this rifle, setting the barrel back is the way to go.
