See my thread on The TCI front end on previous page or so. I am certainly no expert but I will say they are very helpful. I still can't figure out if I am @ fault, but nonetheless TCI came through! I just received my "new" custom made crossmember today but am out of town so can't get to it. Ask lots of questions,you'll need lots of answers.
