It is a 1985 F-150 V8 351 4x4..

After I remove the dash/glove box how hard is it to change once I am to the black cover?
any advice, links to diagrams etc. would be great. I am helping someone and they,(or myself) don't have enough $ for a book, as I am making little $ as it is. I just know how bad it sucks with no heat in this winter weather!!

Thanks in advance!
