for anyone following along with Tyler's project or just sharing knowledge in general....driver's side should be marked as in pic below- stamped at adjacent raised bosses for cruise control bracket and power steering reservoir bracket. In that Craigslist ad, images 10 of 16 is a close up to show the details that driver's side is not marked "TURBO."

Tyler, hopefully you and the seller can work out something. He has had these listed since at least last Fall on northern NJ and NYC craigslist varying the listing to sell as individual parts or a set these past months.
