Will new torsion bars correct that POS, bucket-o-bolts feel I have?

if the front end was completely rebuilt i would look at hi quality shocks like Bilstein,
and a torsion bar upgrade.
I put new .890 torsion bars in my last dart and they made no improvement whatsoever. .96 or 1" for your Cuda
a poor alignment will give you problems
i'm sure the suspension guys will give you some better direction than me
