Normally, you don't need to replace the tbars to restore ride height. The exception are tbars that have significant corrosion that is structurally damaging, and of course snapped tbars.
Although tbars may settle a little over the years, they don't lose spring rate. Your spring plates offer about 3/4 inch of height adjustment range that you can use to correct for this. This is an easy adjustment if you have the tools. If you need more, you can re-index your existing tbars to any height you want. This is a more complex task, but you still don't need new tbars.
Sagging is also caused by tired spring plate bushings. The bushings cold flow over time allowing the spring plates to shift position, and the rear to sag. This happens under the weight of the car regardless of mileage. You may observe the spring plate shaft being significantly off-center of the spring plate cover, that is a sure sign of worn bushings.
Your solution is to replace the spring plate bushings. I recently posted a detailed how-to on this process which included pictures of worn bushings, search under my name.
