Factory Radio Brackets

[orty]

Recently acquired a 2007 Yaris Manual Sedan for myself after getting an 08 hatch for my daughter after she totaled her Echo (this community has been full of great info about both). Love the cars, will probably look into getting one for my youngest daughter when/if her early-90s Camry eats it. However, part of the reason I was able to get the Sedan cheapish was some random cosmetic things -- like the previous owner tried to install a stereo and did a poor job. It was the non-integrated stereo model previously. He put a single-DIN unit into one of those Metra mount and pocket kits, but it doesn't appear to be attached properly to the front of opening so the whole contraption is constantly falling back into the dash. Upon some quick googling, it looks like they didn't move the mounting brackets from the factory stereo, so it's not mounted properly at all.

I'm sure those brackets are long gone, so does anybody know the part number(s) for those so I can acquire some new ones (or have a wrecked one that they want to toss the brackets from)?

Thanks in advance!
