05+ 4wd passenger side diff mount

After I got my 6" procomp, the kit came with their own mounts. I am removing the 6" kit and have the stock passenger side mount. It is an arm with 3 holes. It on one end it has a silver dollar size rubber type washer so the arm has a little play. Well It looks like on one side, something is missing. I cannot find this piece anywhere on the internet to see what was there. I don't even know what to call it or what to search for. This mount holds the front differential on 4WD tacomas.

Anyone have a clue?

 

dang I found it on google images and it just so happens to be on this forum! He has a rubber spacer between the crossmember and the mount though. I need to know the original hardware.
