Door braces

[Kidpaint]

I have what may be too broad of a question when I say universal. What I'm looking for is a door brace that goes from the front of a door opening to the rear but doesn't have to be welded in. Something that could be bolted to say a hinge location and go into the striker bolt location at the rear of the door. To help brace a body that's being lifted without doors to help keep things squared and braced. I searched google and got a lot of house door anti break in devices. Has anyone seen anything like this or made anything? Would have to be able to adjust the length somehow. Or is welding just the best way to go?

Thanks in advance
