Big Block Suspension Question

The 1.08 bars look like a good size for my application. Will likely go that route. I think I will go with a basic tubular upper A arm with built in caster. My K has been re welded and powder coated.
How long do the heim joints typically last in the strut rods versus bushings?
A lot of options to make the old suspension look and drive better.
Will likely have a few more scratches in the TTIs and cus words during install of OEM based suspension than if I ran one of the Coil over conversions. LOL
