Help Needed: 1/2-DIN HU Bracket for Celica

[Celicar]

Want to change the HU on my second hand car from a 1-Din to 2-Din, but the current bracket/casing I have is for 1-Din (and it is something I don't want to retain). Mechanic told me that brackets are not interchangable amongst all car models, so have to look for 1 that fits my ride, and he doesn't have it. I drive a Celica, anyone knows where to get the bracket I need? Or even where I can replace my 1-Din casing, because it is ugly.

 

Thanks for any help!!
