2002 chevy trailblazer_lt
I have a 2002 Chevy Trailblazer. I want to put side mirrors with directionals on it, is there a certain part number that I need to use. I had a 2003 and they were just plug and play. I talked to a auto recycler guy who said there was two different options for the part number for the 2002 year model. Is this true and what part do I need?
