OK, I'm back at this one after a hiatus due to a death in the family. Got a 144x15x2 track under it now, using my 7 tooth driversand a xtra-12 skid with 144 extensions. I had to shorten the extensions one inch, but I have the front mount of the skid in the factory holes, and a real nice attack angle for the track. I will take some pics after I'm done with this portion of the mods, still have to fab rear brackets, and an angled rear flap.
