mild street suspension question

ok guys, I don't usually post on the forums but I read these things religiously. Heres the back story, I have a 1970 Duster with a /6 in it, car only has 46k original miles on it, and has been well taken care of for years. The issue I am running into is the suspension is giving, and the car is my daily driver, so I'm in the process of rebuilding the suspension.

To start I have 4 normal gas shocks that my father picked up online, the ones on the car are completely shot and the front end bounces pretty good over bumps. Second, I recently install some used v8 springs off a dart, which seemed to raise the rear and stop the back from just floating around.

Next for my car will be a disc brake swap which i got from a 73 dart, and since Im going to be doing the work up front I was wondering what would be the best way to stiffen up the suspension to give me the best turn-in and overall performance.

I know these cars arent the best around turns, but i would like to do my best to keep the car on track, and just make it feel more solid. I dont want to turn this car into a drag racer, rather a decent street car that can take a turn at a decent speed.

So far from what I gathered, the first thing i should do is get a sway bar for the front, some new bigger torsion bars, a set of xhd springs out back, and what ever else you guys could recommend to help me.

thanks for the help, mark
