Plastic double din install kit 2000 limited

[superfrog]

Hey folks, I know the usual way to put in a new radio is to use the stock mounting brackets but when I do and screw the bracket in it grounds and I get an alternator whine. I have change grounds and got it mostly tame but if the radio is out of the dash I have no whine. So, I need a plastic mounting bracket but just seeing what others have used. I saw the metes 99-8101 but some have said it doesn’t work.
What are specific brackets you have used?

Thanks

Research ferrite chokes. They work.
