Stepdown Arm Rest Bracket

I am getting ready to make the door panels on my 53 Super Wasp sedan and I will be using the 52 style arm rests in it. I replaced the driver's side door on my car and later found out that the door does not have the bracket welded inside the door to mount the arm rest. It would be much easier to spot weld the correct bracket in than to make one with the correct angkles in it. Does anyone out there have a rusty driver's door they would be willing to cut the bracket out of? I attached a picture of where the bracket mounts to.

Thanks,
Rich
