The Viper shifter is way far forward. The Ebody shifter is about 25 inches back from the bell with a 3 inch offset. It will be tough. The Viper bell is more shallow than the factory Mopar bell. Its shifter is only about 17 inches back from the mounting position. It would be near impossible to get the shifter in the correct location.

If you do this make the motor and trans and older one. The Viper after I think 2000 had no speedo on the trans they all calibrated off the rear end.

If you do this I have a bolt in hydraulic system for that set up.
