I did a quick search of track swaps for a 139" Tundra, didn't see much that would pertain to that topic. Just lost the track on one, and would like to put something totally different, and more readily accessible on it. 600 for a track is way too much money to put into an old sled. Has anyone done a swap from another sled with suspension, drivers, track? If so, what did you use? Thank you in advance for any information.
