I have a 360 with stock Becker CD radio. I removed it to fit an mp3 cable which works great, but after replacing the radio notice it sits too low at the back causing the front to slope back about 10 degrees and thus isn't flush with the front which is very annoying. On further investigation the back doesn't have a bracket keeping it up. Is there a stock spare part for this or something I can use that fits to keep it perfectly in place?
