I think Sky had a bolt in kit where as t.t. you have to drill two large holes and weld pipe in the frame, only one hole out of three bolts up, you can make the stock high pressure hose work and I had to remove the ac pump for more area, belt contact with 33's or the belt would slip and a big cooler is needed for large tires for going slow in rocks or snow. you will need to weld or buy a shaft coupler.
