Although i think two seperate tracks outside the frame would look cooler they just wont work that way. the tracks would fight against eachother making turning next to impossable. The best option and the one ive decided to go with since i dont have a differantial rear end is to go with a track underneath. making the live axle much like a sled setup anyway. It will all work out.......gotta find some shop time though. been dog sitting at my moms house 1/2 hour away since last thursday.
