I have a 2003 Mountain Viper and it has a 144" track on it. Anybody ever extended one to a 151 or a 159. What did you do, who did you buy the stuff from, and how much?
I have a 98 MM with a 151" MPI (Ekholm) Tunnel. They have one for the Viper also and even have a "kick-up" option. Check them out at www.mountainperformance.com
