Hi Folks, I have a 1965 PA28-235 and I am having the interior redone this year. I have heard of, but cannot find any information on headrest kits for the older low back seats. Does anyone know anything about this sort of thing? I am quite a big guy and it would be nice to increase the seat height if possible for the longer trips. If this isn't possible, can anyone recommend any suitable aftermarket seats? Many thanks for any help!
