Vague Steering, How to improve?

Thank you for all the help. I will get a new one. I do not want to rebuild one. Just need to decide which one is best for my purpose. Street driving and trips down the track occasionally. Is the 16:1 PST box the one to get? I have a 15 inch steering wheel and I don't mind the extra effort. I have 195/65-15s on the front
