Been there done that man. If you can get 4 degrees negative driveline angle and 3.5 positive pinion you should be close to center. Mine is almost perfect but it's a 69 Camaro. If you are low like me then it may be best to cut the tunnel now. I don't have driveline vibrations but if I had it all to do over again I would cut the tunnell and run 2-3 degrees of driveline angle.
