Just FYI I am going to try a set of tri y headers on my sb 71 chally. they are built by Schumacher creative services. it looks like a cool setup and they were willing to pay return shipping if they do not work. I can't find headers to fit around the unisteer rack and pinion. if this does not work I will have to build my own or go shopping for stock manifolds. P.S avoid unisteer e-body products. there stuff is killer for chevy but the e-body kit is a POS when they designed the linkage. I will never make a large dollar purchase on impulse again!
