Front suspension and header issues!

[orange prostreet69]

I have a 69 C10 that I put a set of 86 upper and lower control arms on with disc brakes up front. Now my problem is I have bought several different brand headers for our year trucks and all of them are hitting the bushings on the lower control arms. Anyone running these style controls arms and know what headers will clear?? I also am running a manual muncie 4speed trans so the headers will have to clear for clutch linkage too. Thanks! Any help will be great!
