i recently put the advanced adapters/tom woods shaft combo on my jeep. what a great product. it installed as easily as could be expected for someone that has never been inside of a transfer case before.. and it was right the first time, thanks to the pretty good installation instructions big props to the quality of the woods drive shaft too. i haad the weight of the jeep on this shaft at one time.... no problems what so ever, with the exception of a torn boot.
