It's been a long process and many coold winter nights, so what we initially thought was a good solution have changed.
Our first plan was to drive it with a 4-speed Jerico, but when NHRA made it possible to use a 5-speed we decided to swap to a Liberty Equalizer. The Equalizer is not a small gearbox, so we were not sure if it would fit. We used a empty case to see if it was possible. I can promise it was tight but it did fit between the frame rails.
The Viper engine sits way back in the car. To make it possible to shift the gear box we moved the Shifter location forward 5" and fabricated a shifter head with a "bend" to move it additional 2" forward.
