another pinion/driveline angle question

Still have vibration problem. Here is what I have checked with my limited knowledge. Checked the trans angle at the rear housing at driveline seal.
and also at trans pan both appear to be 4 degrees down, using a angle protractor. The angle at pinion taken at the vertical yoke flange appears to be 3 degrees up. Ok, here is another thing. I have air shocks and leaf springs on this stock 56 chev. I have taken all air out of shocks, and no difference, also added 15 pounds which raises car 1/4 inch. Still have vibration. Added air to 35 pounds in shocks which raises car to about 5/8 inch, still have vibration.
Now here is another question. Does the trans. as it sets in car need to be offset between frame rails? I changed from a 3 speed stick to a th350 auto, and strived to get trans. in perfect center of rails, however I have seen somewhere that trans should be offset towards the passenger rail? Thanks.

have not checked it, just thought it may be. Also, one member said to run engine up to high rpms in park or neutral and see if the vibration is from torque converter and or flex plate. Did that and did not notice any vibration.
Thanks

you have checked the angle on the driveline front and rear on the vertical.
what about the horizontal?
if trans is centered and pinion is way offset?

I used a protractor with a needle for the vertical at end of trans. and pinion flange, but not sure how to measure drive line with the protractor. I think I would come up with somewhere at 5 degrees down simular to end of trans. checking in the horizonal plane.
But where to put protractor? Middle of driveline? At either end? Also I`m not sure about rear end being offset, I am only going by what I hear on the forum.
Thanks
