If you don't get anything here you might try calling Drivetrain.com in Las Vegas. They have parts and have been very knowledgeable and help full for me in the past. I called on a weekend expecting to leave a message and the guy answered and said it was his turn to take the phone home. Got my answers and got my truck back together.
