i have a 73 camaro that is an auto t-400, i also have a viper t-56 who maked a kit that is not very expensive like the kiesler kit. what spline is the viper? are they different form the camaro ones. thanks

Tyler at ATS in Las Vegas makes an excellent, all inclusive kit for the installation of a T-56 into the F platform. He is a member here on Team Camaro, goes by the name "Tito-Jones"....give him a call.

And FYI, the output spline is of the 30 tooth variety. And yes, the Viper box is much different than that of the Viper box itself.
