Okay, many of you may have known this already; I had to find out the hard way. Apparently they cannot make a double cardon (2 Ujoints at each end) driveshaft big enough to make "HD" because it would hit the trans. pan. On my 4th or so launch "ever" I busted the Ujoint housing nearest to the output of the transfer.
If anyone has a stock driveshaft for sale I would definately be interested.
