Upper control arms

I'm doing work on my family owned d1973 340 duster and looking for some advice on the suspension advantage of doing tubular upper control arms or stock with better bushings..want to use it for weekend rides ..I do like to drive hard..I'm new to this forum and would appreciate any advice
Depends on the condition of your uppers. Personally I'd upgrade to the tubular. Will there be a huge advantage, not on a street car but combined with other suspension upgrades, you can make it handle pretty well.
