I have a bench seat in my 71 and was curious if these headrests are the same as on 71 bucket seats?

The Bench headrests and Bucket headrests are different. The bench uses a center "blade" and the Bucket a pair of posts. However, it seems that from 69 to 72 they are the same (need to change the cover). So, if you find a pair from another year you should be able to recover them. Looks like any one from a GM "A" body could work. If you are asking because you have a pair of bucket headrests, e-mail me, I'm looking for a pair.
