Power Steering Bracket ('65 small block)

Listed in FSM as 1945384 power steering bracket. I have seen it superseded as 2946737 and called an idler pulley bracket. I don't know if the two parts are the same part or not. Even if a different design, the 737 might work (I have not seen one yet).

By the way, 1945384 is actually a 2 piece bracket. I don't know why they share the same part number. I have one of the brackets (the front one). I found 1945384 on ebay, but it was the front bracket only. I need the rear bracket. Or in the drawing from the factory service manual, it is the top bracket. The car is in Mexico, shipping could be here (Mexico) or to the USA. I could probably fabricate one in Mexico, cheaper than purchase plus shipping, but it looks like a crazy shaped part and that would not be easy. Thank you.
