This is a pretty involved job. I always tell my customers to go to the local Library and check out the Hughes or Chilton's Manual. It is free and will save you a lot of time and money. I could explain how to do this. But I am sure that myself or any other Expert on here would be going off of memory, and could leave some steps out. That is why I always suggest the library. Checking the book out is free and I am sure that it will save you a lot of time.
