There is a lot of discussion about using mustang 2 (MII) IFS kits of various kinds if you search or browse.
The real question you need to answer before much advice can be given is what do you want the finished product to be? A truck with modern power? A weekend cruiser? A touring vehicle? One thing to be aware of is that the MII kits that are listed as "stock height" actually lower these trucks 2"-4". They use stock height spindles, thus the name.
What you want to have when you are done really affects what upgrades make sense and which ones will give you trouble.
