installing new arms is way easier than new bushings if you think you can tackle that. I'd just skip that one upper bushing in the diff as you aren't likely to notice it. lower arms are by far the biggest impact on handling.
super looking forward to this build.
(side note, we've been having random issues with upside down photos but it has to do with how orientation code is saved in different systems and thus beyond our software. I've found that if I alter the pic at all in my laptop and save, it'll load properly if you're using a phone it's more complicated than i can fix them for you as needed.)
how rusty is the truck? is you charcoal system intact? how's your fuel economy looking? 4.0 or 2.5?
you should put some basic info on your truck in your signature.
