When you are road ready, what is your goal for this truck?
Around town in style?
Highway cruiser?
Cross country road trip?
This question needs answered in order to point you in the best direction. Also please provide what engine is pushing all this. If your existing driveline is in decent shape, I would strongly recommend just getting the truck drivable and just drive it. The reason for this is to really make up your mind about the truck’s setup. Many change their minds once they get some seat time. I know I fell into that category.
Better to change your mind before you really start then after spending a lot of time changing things from the start.
