How to remove the dashboard?

There are at least 25 steps to remove this. You need a shop manual with diagrams. Way too much to type out for you

Try Ebay for a good used reasonably priced shop manual. If no luck there try Faxon Auto Literature in Riverside CA for a reprint. I've bought from them. Good quality and reasonable prices. If you need to repair or replace something on the dash you need to get at it from underneath. Hope that helps! Jim
