Hi guy's I was looking at a viper that was from when they first come out, Somebody had converted it to a mountain sled from a trail model, it has a long track and the a arms and all the fancy stuff..... I was just curious on if the chain case lengths up front there are going to be any different or if the chassis would be roughly the same besides stuff like the A arm lengths/track/tunnel? I just ask that as it has a 2.5" track on it and I never took a look but I'm wondering if they stuck a 2.5 on it as it was all that would fit or because they did not want a 3". Thanks!
