stock upgrade possible?

that's the thing. Im pretty uneducated when it comes to the smaller bits and pieces. I don't have anyone to guide me, aside from the tips I read about here. I often find myself asking questions that are either really dumbed down or way overthinking things!

The Hotchkis TVS kit comes with:
# 1112 Geometry Corrected Tubular Control Arms
#14385 Adjustable Strut Rods
#16385 Adjustable Steering Rods
#22385 Lightweight, Durable 1 1/2" Tubular Front Bar, Adjustable 1" Tubular Rear Bar
#24385 Geometry Corrected Leaf Springs

with that in mind, what else would I need on a car that has no suspension on it? There appears to be no spindles, hubs and the like, so would I need to buy old style spindles and stuff or is that available at an autoparts store?

EDIT:
just found a video of the install on a chally. All the modifications are at the wheel, so I still got to find original spindles and hubs and then get a brake kit. Still old style steering boxes and stuff..still a possibility though, just gotta figure out how to get all the parts I need
