64 valiant 4-door Street legal drift car

So I have a 64 valiant 4-door that I'm planning on turning into a turbo 323 (bored 318) drift car, but my biggest question is, how would I go about getting better suspension goodies? So far the only things I've seen so far are full K-memeber swaps and I'm not exactly equipped to dig THAT far yet, I have the knowledge to, just not the tools due to some shitty circumstances. So basically, is there a way to upgrade my suspension enough to handle getting sideways without doing a full k-member? If so who makes the parts?
