66/67 A and B body Bucket seat frames and slides

year cars so could the fastback have 66 back bucket frames or can you only use headrests for 67 on back frames that had headrests

I'll post a 66 and a 67 frame photo for you. They will look the same when covered, mount the same on the base (which is the same) and is designed for the metal back and sides. ( Which are the same as well)
