Well the metra dash kit from installer.com has the head unit and everything else included like the brackets. Maybe give em a call or an email and see if they can sell you just the bracket. The kit is only $30 so maybe do that.
Haha right. They have a metra kit for my car its still over $150. It is because on my car you have to replace the a/c controls and vents. I bought the OEM JDM kit which cost $150 for the trim and $170 for the a/c.
