560 SL passenger side wiper arm

[DOCJBK]

Hope someone can help with a part. I took the "Beast" out in the cold just to warm her up and have a little fun and when I hit the wipers, the passenger side wiper arm broke. I hope someone out there has or knows where I can get a used arm. The new ones (forgive the pun) are an ARM and a leg. Can the old one be welded, it broke at the mounting? Thanks for the help.
