So I finally got my 1350 cv shaft from High angle driveline (Jesse is the best!) Well i got my angles here, the pinion is at 9 degrees, shaft is running at 17. Difference of 8 degrees.I already have a 2degree shim in there from before which is coming out. I was planning on getting a zero rate and having it machined down to a 6 degree taper. Which when taking out the old shim would leave a 4 degree angle, Jesse said it should bre 2-3 degrees for no vibes. I am reluctant to cutting the perches on it because I like playing around with it. Should I just take the zero rate and have a taper put in it and call it good?
