73 Duster 340 Suspension Recommendations

Hey gang,

Looking at some small handling upgrades for my car and looking for some feedback suggestions- not a drag race car would like to improve handling on road

Engine is now 418 Stroker/aluminum heads and intake so a lot less weight than stock 340 setup.

Currently front suspension:
.870 T bars Factory
Factory Sway bar- 20.6mm with poly end links/poly bump stops
Monroe’s
Factory upper/lower control arms

Rear:
SS springs
Monroe shocks
Will have welded frame times on shortly

Looking at either QA1 non adjustable or bilsteins for shocks all 4 corners and would there be any benefit increasing sway bar size or just keeping what I have.
Eventually I want to run qa1 upper control arms, my current UCA bushings are cracking so I may just pull the trigger now. I also may upgrade to a 1.03 T bar.

Thoughts/suggestions, mainly focused on the shocks and possible sway bar upgrade if it makes sense.
