I have a 1995 Mustang I recently did a 4.6 swap in and an 03-04 cobra IRS swap in. I have a vibration in what feels like the rear end of the car when I let out on the clutch when I first start to move. Im not sure what the cause is yet so looking for some input. I did put a new clutch in the car when I did the swap. It feels like the rearend of the car like I said. I don't have any vibration in the clutch pedal that I can tell. Hope it doesn't have to do with the clutch. I know I had this clutch in my other car for about 3000 miles before I tore the car apart and I never had any problems then. I have long tubes on so I am sure it is goint to be a PITA to remove the transmission with those on if it is the clutch. Thanks for the help
