What is the name of this ceiling fan part?
Sad to say but the time that it will take you to find the right part (it looks like a part called a hanger) and track down the obscure supplier who made the piece, organise replacement and shipping and get it back will far exceed the time and cost of you taking a small piece of mild steel plate available from your local home improvement or car parts store, drilling the holes you need and bending it in a vise.
