I'd like to add the T56 Magnum is a bit longer and makes any driveshaft angle problem worse. On the One Lap Camaro we had a u joint angles of 9 degrees front and rear, had a bad vibration at 57 mph. Reducing it to 8 deg is getting us by, but the trans needs to be raised to fix it totally. With the trans tail down, the pinion has to be nose up, this puts the driveshaft rising to the rear.
We have the ATS crossmember and it's the lowest thing on the car, lower than the exhaust.
