I use Baker's Gas in Monroe but their closest location to you is their main location in Lincoln Park. They exchange, and once you have a cylinder with their label you don't have to worry about hydro dates. AIH will fill them (in date) but I think only Ann Arbor is open.
If those tanks are brand new or newly refurbished, I just ran into a little bit of a hassle with an unlabeled refurbished nitrogen tank from AIH. Lack of a label dragged literally 5 people into it, 4 in Monroe and 1 on the phone in Lincoln Park.
