68 and 69 rocker spears are the same, 73-up are different! The 68-69 spears are thinner and come to more of a point, the 73 style is thicker and has more of a bull nose. Many people use Camaro spears, not even close. I have a picture around here somewhere of both types. EDIT: here is the picture, 68-69 is on the left...

The funny thing about science is that if you change one miniscule parameter you change the entire outcome to the way you want it.
