Ok I'm getting sever vibrations so bad that the front of the driveshaft is hitting the driveshaft loop. The car is a 98 cobra with 03 swap minus the IRS went solid 8.8. That being said the drive shaft is out of the 03 cobra. the pinion angle is at +2 degrees. the driveshaft appears to be too short the slip yoke is showing an inch and half to two inches out of the tail shaft of the T56. I've heard 3/4" is the max. could that be the cause of this? the installation instructions on the torque arm reads in the end that the stock drive shaft may not be balanced well enough for this set up. I don't understand how its too short i've read a million write up on this site of 03 cobras going SRA and SN95 cars going IRS and none of them say anything about having to swap Driveshafts. Can someone please make sence of whats going on here??????

Wut he said.

But yes, that might be the problem.
T56 only = stock length ds
IRS only = stock length ds
IRS + T56 = 03 cobra length ds
