I heard from some local guys that go out west alot, that you can re-locate your skid to accept a 136" track. Has anyone done this on theirs? I was thinking about cutting down a 15x136x2" to 13.5x136x2" to go out west. They said it has been done without tunnel extensions, but you have to have drop brackets, which I have. 9-tooth drivers are probably going to be a must also. If anyone has any insight or experience please let me know.
