Adaptors

so I bought some rallyes for my dart 15x6.5. Went and got some 215/60/15 bf Goodrich radials. Came home to mount them and realized I bought the wrong bolt pattern. I thought my car is 5x4 1/2 but it’s 5x4. Has anyone ever used an adapter to go from 5x4 to 5x4 1/2?? Let me know if you have any recommendations. Definitely feeling like a rookie!
