I have a set of 68 B body bucket seats and a set of bucket seat headrests and need to know what needs to be done to the seat frames to use the headrests. The seats have never had headrests. I found a kit through one of the parts suppliers that says it's a headrest mounting kit for bucket seats. If someone can post a picture of what the seat frame is supposed to look like for buckets I would appreciate it. It seems there should be more to it than screwing a plastic piece down under the chrome bezel. Thanks in advance.
