Hey Nailbender, if your still going to measure your driveline angle I found this tool to be the easiest to read and use. I also pulled the drive shaft out to try and get as accurate a reading as possible. I had put a set of ron morris mounts in trying to lower the front of the engine thereby raising the tailshaft, It only changed it about .5 degrees, not as much as i was hoping for. Right now my engine trans is pointing downwards at 3 degress and the the rear is at 0. I cant raise the aod trans any more as it hits the floor. I have what i think is a pretty noticible driveline vibration that i think is caused by the current angle setup, next is try to shim the rear up a degree or 2 and see if that does anything...Anyways, i really like the digital readout of this tool vs the other driveline angle finders i was using. Post up what your angles are if yu can, and is your car now vibration free with the regualr trans mount?
