I have '67 Nova buckets in my '69 and I love them...they are super comfy and just look nice IMO. However I would like to, if possible, add headrests to them as a safety measure...if you have ever known anyone with serious whiplash you will know why I want to add them. Anyway I have seen complete headrest assemblies in a few of the repop cat.'s and was wondering if it is possible to retro fit a set to my buckets...BTW the buckets need to be recovered so that part is not an issue. Thanks in advance.
