Old man with old car, new here with questions

I forgot to respond to you're comments on the starter relay, which I will add to my list of things to do. I do know the leaf springs are flat. Even with new shocks it sways badly. Would over / helper springs help short term or is the only fix new leaf springs?
I will get my car back from my welder friend this week and I hope to work on it some more. Thank you.
