Mine seemed low too , so I installed the trans using a large , dense piece of foam rubber around the shift tower and on top of trans , used a lift at work with a jack stand under the trans cross member , loosend the cross member bolts and droped the lift slowly and then tighted the bolts back up and seems much better now . Basicly reforming the trans tunnel a little and The cross member alot tighter to floor pan . Thers still enough clearance that nothing touches . Way better header clearance now , and no doubt better drive line angle .
