I recommend using the SEARCH option in the header toolbar up top. I've been reading posts on seat belts, headliners, and glass installation questions and I myself have posted step-by-step procedures for all of this. I'm not trying to be condescending, just letting everyone know that it *might* be easier to search instead of waiting for someone to answer.
