How hard is it to fix door and is it worth getting

[doaner70]

Ok my buddy has a 70 c10 at his junk yard and both doors are super nice no rust other then where the top hinge bolts up. He wants 100 bucks for both. Went to take them off and both top hinges is rusted threw the doors. Are the worth fixing or better off finding better ones. And how hard are they to fix. I need 3 doors and in these parts there hard to find good doors.
