I have a 70 Chevelle just set in motor with 4l60 empty case just for setup. I'm using the stock trans crossmember. With my angle finder on valley plate I'm 4* down and at tail shaft of trans I'm at 0 and at 0 at rear end. Im sitting on suspension but the front end may go down another 1" Does anyone see any problem with this? I only have the crossmember tab tacked in so I can move it up another * if I need to. Thanks for any help input.
