74 Duster, full build 6.4 conversion in Australia, rebuilding front end questions!!

About to start rebuilding the suspension, i have the PST graphite kit that has all the balljoints and rubbers etc. Do i need new pivot pins or just re use the original with new bushes etc? Is this an item that wears out? As new pivot pins are not cheap given what you are getting. I will also brace and powder coat the arms.
Anything to look out for with the arms etc?
