Has anyone changed their mind about AA/SA index?

It is not my belief that the four link was done to spite anyone or to gain an advantage. It is just a reality that the way the newer independent rear suspensions are configured does not allow for a workable solid axle conversion. The GTO's and Corvette's have been allowed to run torque arms, etc. for quite some time, so this is nothing new. When I started working on my BIW Camaro in 2010, I sent photo's to GM of a torque arm under the car. I got no response. When the 2012 COPO prototype was at the PRI I asked the NHRA if that would be legal for Stock Eliminator. They said yes, but with a 12-bolt. So that is what I went home and built. I am still waiting for the new engine specification to be published by the NHRA.........
