Are you wanting to do trailing arms like the 60-72 truck? There are two options for that, Porterbuilt an CPP. The factory arm cross member won't fit the square body frame.

I have Porterbuilt kit on order, which I'm using factory arms with along with a factory 71 rear axle. Hopefully it should ship this week but I have a lot of work to do before the install.
