I've serviced and rebuilt many of these.
If your damper is plastic, I'd be surprised it has survived this long as the plastic tended to go a bit brittle over time, often the upper legs are all that's holding it in shape, so removing is often the cause of them leaking.
A hard body damper I'd the way to go.
Spring conversion will be fit and forget, iirc you might need to mod or come up with a way for the springs to seat properly.
Rather than the Judy Jax, you could look at the other style of elastomer fitting, a metal skewer. That way you just need washers between each elastomer.
