I'm looking at a buildsheet for a 70 SS and do not see two options on it. The first is the f41 (front and rear sway bars) and the second is the n10(Dual exhaust). Refering to the tech info(all SS have)it should be on the sheet right? It does have the g67,zj7,LS5,z20,m40 and p90. I' not sure but again they should be on the buildsheet right.
