Default another driveline angle question

Found tons of information regarding normal and 4X4 driveline angles, but very little on lowered vehicles. The question, 66 coupe dropped roughly 2"'s (coils+shelby drop, mid-eyes+ 1" blocks). Knowing you have to compensate for the lowered vehicle, and must have 0*'s of angle with opposing front/rear angles no more than 3* of each. Which is best, raise the tail of the tranny, or raise the pinion nose? The 4.5 leaf should reduce or eliminate the wheel wrap. So, which is best? thoughts, or experiences?

ok, you reduced the angle of the diff and trans to the shaft by almost 2 degrees.

if you raise the trans yoke by around 1" and lower the yoke on the diff by around 1/4" you will be close to your previous angles.

if you raise the trans only you will increase the angle of the shaft at the trans more than you will at the diff because you are not changing the elevation of the trans like you did when you lowered the car, you are changing the elevation of the yoke only, which changes the angle of the entire trans relative to the driveshaft. its a complicated but if you draw it on paper you can easily see what i mean.
