Driveline angles and launch shudder.

Driveline angles and launch shudder.
I have a slight launch shudder on acceleration. I have lower it 3/5 with a rear McGaughy's flip kit. I measured the angles today. My front angle is 6 degrees, driveshaft 0 degrees, and rear pinion 6 degrees. My working angles would be 6 and 6. I believe that is too much. I think I need to shim the transmission mount to decrease front angle which should raise the driveshaft angle. I also need to change the rear pinion angle by tipping pinion nose down to decrease angle. Does it sound like I doing this right? Which shim do I need for the front and rear?

You should probably explain where exactly your measurements came from.When you say 6 degrees is that positive negative also what are you 6 degrees out from could be the ground,chassis,crankshaft?

OK so a real quick step by is to:
-Get the driveshaft parallel to the crankshaft or close as possible.
-Now measure the difference if there is any of the pinion to the driveshaft in relation to the ground.If I understand correctly you have a pinion that is pointed 6 degrees towards the ground with parallel being the start 0 degrees.
-Now your driveshaft is 6 degrees up from parallel to the ground correct?
-Get the driveshaft parallel to the crankshaft or close as possible.
-Now measure the difference if there is any of the pinion to the driveshaft in relation to the ground.If I understand correctly you have a pinion that is pointed 6 degrees towards the ground with parallel being the start 0 degrees.
-Now your driveshaft is 6 degrees up from parallel to the ground correct?
