Tubular control arms vs rebushing

My 71 dart is starting to get a bit rattly in the front, I can see the strut rod bushings are toast so I'm imagining everything ought to be gone through. I saw mancini has a bit of a deal on parts and I got a bit of a bonus from work so I'm in a good spot to get this done. Obviously, all new modern parts are going to improve handling ( tubular upper and lower arms, adjustable strut rods). But how much better...and it seems like new parts would just drop in compared to replacing bushings. So better handling and easier install, but $1000 dollars worth?

I don't do much more than occasional 'spirited' driving, it's not quite a daily driver but more than a fair weather weekend car
Replace the worn strut bushings.
Check the other parts for wear. It's not that hard to check each one. Replace the ones that are worn.
A worn strut bushing does not mean the UCA bushings or ball joints are worn. It could relate to wear on the LCA bushings.

If you want to spend money, install a front anti-sway bar if it doesn't have one. Even a stock one will be noticible.
If you want to spend more, then larger t-bars like .990 or even 1.03 and a larger front anti-sway bar would be the next steps.
