Hi, welcome to Just Answer. I’m Ron and I’ll be helping youtoday.Before we get started though, Please understand that I don't knowyour skill level or tools you have to assist us. Also understand thatI can't see, smell, hear, or touch the vehicle either, so patience isappreciated.

Sometimes I have to give you bad news that I know youdidn’t want to hear, so please don’t shoot the messenger.
