For safety reasons, I'd like to add seats with headrests to my 65 SS (w/buckets). I don't want the aftermarket race seats - just not OEM or NOS enough. Was thinking 66 Impala buckets but those RARE! Then thought maybe 69 Camaro buckets which I'm luke warm on - still factory, but I don't like the idea of driving a Campala. Any ideas? Given the choice between whiplash and vintage, I'll go the safer route and live with the inevitable stinkeye from the purists.
