New old stock from a dealer that went out of business a long time ago. Part number 994659. Books say 1974-1978 but I think you can use these on any Squarebody. These are the just the head mirrors. Both NEW in the original GM Box with instruction sheet and all the mounting hardware. Look online to know what they fit for sure so the info I have is to the best of my knowledge correct but please do your own research and make sure this is what you are looking for. In great unused condition.
