bepends on your budget..
even bolted in ball joints can be 30 years old..
i'd look it all over.. and me myself would replace the balljoints now if there is any question.
tierods /etc are easy to replace later..
once you take it to be lined up. they'll tell you whats loose..
but you ARE down to a bare frame..
it might be the best time to look at the a arm bushings/balljoints
better question is Did the truck look like it was mantained correctly before you got it
if yes, it's more than likely safe to bet on the parts under there to be ok.
if not.. well
