The confusion I'm seeing in the responses to your posts stems from the up/down relationship of your angles. The standard way of naming the relationship of "up or down" is in relationship to the driveshaft. You called the engine trans angle up, but your transmission should be referred to as 5 degrees down angle and the pinion would be referred to 3 degrees upward angle , as you have correctly stated.
That being said, it sounds like now your pinion angle is .5 degree down in relation to the engine trans shaft centerline angle. Nice.
I too had the poly locks, and did not like the vibration transmitted to the car through them. I called Schumacher and ordered their torque shaft kit and a fresh set of stock rubber mounts, I like this much better, but beware. They will lower the front of the motor slightly as they are thinner than the poly's. It is likely enough of a difference to change the centerline relationship between the engine trans and rearend. Double check once you have swapped them in.
