Looking for 67-72 front ifs for c10.

[tmg619]

Im looking for 67-72 fromt ifs. I dont know whoch one i should get. Some are very expensive. I am ok with bolt in or weld in. I am capable of doing either one. Finding a used one would be nice. I have seen porter builts amd theres another company called helix. They both have good reviews i just dont want to spend a crazy amount of money. I just wanted the handling that it would give me. Is there any other options like swaps from other vehicles.
