I have finally got to work on my cut-down frame. Its mostly put back together. A friend said he pulled a rear drive-shaft from a Ford truck that is the right length I need (33 to 34 inches) , I`ve not seen it yet. My question is, are the stock drive-shafts and u-joints considered fairly stout? I don`t remember anybody ever say anything about breaking one and was just wondering? I`m not planning on getting to wild, but I do have a twenty year old boy.
