Hi there! I bought a 77 c10 with a tt 5.3. Some parts of the build were done somewhat nicely, some not so much. Suspension is one of the not so much areas, I’m looking at options for redoing it. It currently has a flip kit with stock components. I’m considering four link but it’s spendy. I’m looking for good street/strip options. I don’t want to just cheap out but want something not overly spendy to do both those things. What are your recommendations?

 

Have you tried GM Square Body. (I can't post the exact link) Forums that are specific to the c10, and the third generation of that truck, will be able to answer your question more helpfully.
