No, as long as it's not badly rusted. I can bead blast all small parts and paint. I figure the spring is needed most when seat position is changed and since I'm the only one driving my car, who cares about moving seat.
Is it possible to purchase missing seat track hardware for a '65? I need a pair of those white plastic guides and one of those rollers. They were missing when I took the track apart to clean and paint them.
