The 79-82 Ford Mustang 5.0 used the Autolite 2150 2-barrel carb. So if you’re searching online zero in on the “2150” and not just general Autolite 2-barrels because the amount of info can be confusing.
This link contains the pdf for that carb with detailed info/adjustment details that should help you get back to running smoothly again:
