what's the angle that the front and rear pinions (HP 30, 8.8) should be at? Angle based off of the driveshaft angle or the ground? sorry its a dumb question just wanting it right. Eye balled it the first time but when upgrading I want to be sure

Do you have CV type driveshafts or non-CV type driveshafts. That makes a big difference.

Please do some reading.
