AMC 304 / 360 / 401 power steering bracket. The picture is what you will be getting if you buy; one single bracket. To mount the pump, you need a few other parts, but whole sets are expensive, so maybe you can buy this and add the other parts, or maybe you have the other parts and need this particular bracket in the assembly. 

This came off a 304 I had rebuilt and I found a whole set afterwards which made my life easy. I'm hoping this is something someone out there is looking for.
